+/************************************************************************
+## Blocks Module
+
+You hate having to lookup [Data Values][dv] when you use ScriptCraft's
+Drone() functions. So do I.  So I created this blocks object which is
+a helper object for use in construction.
+
+### Examples
+
+    box( blocks.oak ); // creates a single oak wood block
+    box( blocks.sand, 3, 2, 1 ); // creates a block of sand 3 wide x 2 high x 1 long
+    box( blocks.wool.green, 2 ); // creates a block of green wool 2 blocks wide
+
+Color aliased properties that were a direct descendant of the blocks
+object are no longer used to avoid confusion with carpet and stained
+clay blocks. In addition, there's a convenience array `blocks.rainbow`
+which is an array of the 7 colors of the rainbow (or closest
+approximations).
+
+The blocks module is globally exported by the Drone module.

+/************************************************************************
+### Drone.arc() method
+
+The arc() method can be used to create 1 or more 90 degree arcs in the
+horizontal or vertical planes. This method is called by cylinder() and
+cylinder0() and the sphere() and sphere0() methods.
+
+#### Parameters
+
+arc() takes a single parameter - an object with the following named properties...
+
+ * radius - The radius of the arc.
+ * blockType - The type of block to use - this is the block Id only (no meta). See [Data Values][dv].
+ * meta - The metadata value. See [Data Values][dv].
+ * orientation (default: 'horizontal' ) - the orientation of the arc - can be 'vertical' or 'horizontal'.
+ * stack (default: 1 ) - the height or length of the arc (depending on the orientation - if orientation is horizontal then this parameter refers to the height, if vertical then it refers to the length ).
+ * strokeWidth (default: 1 ) - the width of the stroke (how many blocks) - if drawing nested arcs it's usually a good idea to set strokeWidth to at least 2 so that there are no gaps between each arc. The arc method uses a [bresenham algorithm][bres] to plot points along the circumference.
+ * fill - If true (or present) then the arc will be filled in.
+ * quadrants (default: `{topleft:true,topright:true,bottomleft:true,bottomright:true}` - An object with 4 properties indicating which of the 4 quadrants of a circle to draw. If the quadrants property is absent then all 4 quadrants are drawn.
+
+#### Examples
+
+To draw a 1/4 circle (top right quadrant only) with a radius of 10 and
+stroke width of 2 blocks ...
+
+    arc({blockType: blocks.iron, 
+         meta: 0, 
+         radius: 10,
+         strokeWidth: 2,
+         quadrants: { topright: true },
+         orientation: 'vertical', 
+         stack: 1,
+         fill: false
+         } );

+/************************************************************************
+### Copy & Paste using Drone
+
+A drone can be used to copy and paste areas of the game world.
+
+#### Deprecated
+As of January 10 2015 the copy-paste functions in Drone are no longer
+supported. Copy/Paste is:
+
+1. Difficult to do correctly in a way which works for both Minecraft 1.7 and 1.8 
+   due to how blocks changed in 1.8
+2. Not aligned with the purpose of ScriptCraft's Drone module which is to provide 
+   a simple set of functions for scripting and in-game building.
+
+### Drone.copy() method
+
+Copies an area so it can be pasted elsewhere. The name can be used for
+pasting the copied area elsewhere...
+
+#### Parameters
+
+ * name - the name to be given to the copied area (used by `paste`)
+ * width - the width of the area to copy
+ * height - the height of the area to copy
+ * length - the length of the area (extending away from the drone) to copy
+
+#### Example
+
+    drone.copy('somethingCool',10,5,10 ).right(12 ).paste('somethingCool' );
+
+### Drone.paste() method
+
+Pastes a copied area to the current location.
+
+#### Example
+
+To copy a 10x5x10 area (using the drone's coordinates as the starting
+point) into memory.  the copied area can be referenced using the name
+'somethingCool'. The drone moves 12 blocks right then pastes the copy.
+
+    drone.copy('somethingCool',10,5,10 )
+         .right(12 )
+         .paste('somethingCool' );

+## Drone Plugin
+
+The Drone is a convenience class for building.
+
+It uses a fluent interface which means all of the Drone's methods return `this` and can be chained together like so...
+
+    var theDrone = new Drone(self);
+    theDrone.up().left().box(blocks.oak).down().fwd(3).cylinder0(blocks.lava,8); 
+
+### Constructing a Drone Object
+
+Drones can be created in any of the following ways...
+    
+ 1. Calling any one of the methods listed below will return a Drone object. For example...
+         
+        var d = box( blocks.oak )
+
+   ... creates a 1x1x1 wooden block at the cross-hairs or player's location and returns a Drone object. This might look odd (if you're familiar with Java's Object-dot-method syntax) but all of the Drone class's methods are also global functions that return new Drone objects. This is short-hand for creating drones and is useful for playing around with Drones at the in-game command prompt. It's shorter than typing ...
+    
+        var d = new Drone(self).box( blocks.oak ) 
+        
+   ... All of the Drone's methods return `this` so you can chain operations together like this...
+        
+        var d = box( blocks.oak )
+                  .up()
+                  .box( blocks.oak ,3,1,3)
+                  .down()
+                  .fwd(2)
+                  .box( blocks.oak )
+                  .turn()
+                  .fwd(2)
+                  .box( blocks.oak )
+                  .turn()
+                  .fwd(2)
+                  .box( blocks.oak );
+    
+ 2. Using the following form...
+
+        d = new Drone(self)
+    
+    ...will create a new Drone taking the current player as the parameter. If the player's cross-hairs are pointing at a block at the time then, that block's location becomes the drone's starting point.  If the cross-hairs are _not_ pointing at a block, then the drone's starting location will be 2 blocks directly in front of the player.  TIP: Building always happens right and front of the drone's position...
+    
+    Plan View:
+
+        ^
+        |
+        |
+        D---->
+      
+    For convenience you can use a _corner stone_ to begin building. The corner stone should be located just above ground level. If the cross-hair is point at or into ground level when you create a new Drone() with either a player or location given as a parameter, then building begins at the location the player was looking at or at the location. You can get around this by pointing at a 'corner stone' just above ground level or alternatively use the following statement...
+    
+        d = new Drone(self).up();
+          
+    ... which will move the drone up one block as soon as it's created.
+
+    ![corner stone](img/cornerstone1.png)
+
+ 3. Or by using the following form...
+    
+        d = new Drone(x,y,z,direction,world);
+
+    This will create a new Drone at the location you specified using x, y, z In minecraft, the X axis runs west to east and the Z axis runs north to south.  The direction parameter says what direction you want the drone to face: 0 = east, 1 = south, 2 = west, 3 = north.  If the direction parameter is omitted, the player's direction is used instead. Both the `direction` and `world` parameters are optional.
+
+ 4. Create a new Drone based on a Location object...
+
+        d = new Drone(location);
+
+    This is useful when you want to create a drone at a given `org.bukkit.Location` . The `Location` class is used throughout the bukkit API. For example, if you want to create a drone when a block is broken at the block's location you would do so like this...
+
+        events.blockBreak( function( event ) { 
+            var location = event.block.location;
+            var drone = new Drone(location);
+            // do more stuff with the drone here...
+        });
+
+#### Parameters
+
+ * Player : If a player reference is given as the sole parameter then the block the player was looking at will be used as the starting point for the drone. If the player was not looking at a block then the player's location will be used as the starting point. If a `Player` object is provided as a paramter then it should be the only parameter.
+ * location  : *NB* If a `Location` object is provided as a parameter, then it should be the only parameter.
+ * x : The x coordinate of the Drone (x,y,z,direction and world are not needed if either a player or location parameter is provided)
+ * y : The y coordinate of the Drone 
+ * z : The z coordinate of the Drone 
+ * direction : The direction in which the Drone is facing. Possible values are 0 (east), 1 (south), 2 (west) or 3 (north) 
+ * world : The world in which the drone is created. 
+  
+### Drone.box() method
+
+the box() method is a convenience method for building things. (For the more performance-oriented method - see cuboid)
+
+#### parameters
+
+ * b - the block id - e.g. 6 for an oak sapling or '6:2' for a birch sapling. Alternatively you can use any one of the `blocks` values e.g. `blocks.sapling.birch`
+ * w (optional - default 1) - the width of the structure 
+ * h (optional - default 1) - the height of the structure 
+ * d (optional - default 1) - the depth of the structure - NB this is not how deep underground the structure lies - this is how far away (depth of field) from the drone the structure will extend.
+
+#### Example
+
+To create a black structure 4 blocks wide, 9 blocks tall and 1 block long...
+    
+    box(blocks.wool.black, 4, 9, 1);
+
+... or the following code does the same but creates a variable that can be used for further methods...
+
+    var drone = new Drone(self);
+    drone.box(blocks.wool.black, 4, 9, 1);
+
+![box example 1](img/boxex1.png)
+    
+### Drone.box0() method
+
+Another convenience method - this one creates 4 walls with no floor or ceiling.
+
+#### Parameters
+
+ * block - the block id - e.g. 6 for an oak sapling or '6:2' for a birch sapling. Alternatively you can use any one of the `blocks` values e.g. `blocks.sapling.birch`
+ * width (optional - default 1) - the width of the structure 
+ * height (optional - default 1) - the height of the structure 
+ * length (optional - default 1) - the length of the structure - how far
+   away (depth of field) from the drone the structure will extend.
+
+#### Example
+
+To create a stone building with the insided hollowed out 7 wide by 3 tall by 6 long...
+
+    box0( blocks.stone, 7, 3, 6);
+
+![example box0](img/box0ex1.png)
+   
+### Drone.boxa() method
+
+Construct a cuboid using an array of blocks. As the drone moves first along the width axis, then the height (y axis) then the length, each block is picked from the array and placed.
+
+#### Parameters
+
+ * blocks - An array of blocks - each block in the array will be placed in turn.
+ * width
+ * height
+ * length
+
+#### Example
+
+Construct a rainbow-colored road 100 blocks long...
+
+    var rainbowColors = [blocks.wool.red, blocks.wool.orange, blocks.wool.yellow, blocks.wool.lime,
+                         blocks.wool.lightblue, blocks.wool.blue, blocks.wool.purple];
+    
+    boxa(rainbowColors,7,1,30);
+
+![boxa example](img/boxaex1.png)
+
+### Chaining
+
+All of the Drone methods return a Drone object, which means methods can be 'chained' together so instead of writing this...
+
+    drone = new Drone( self ); 
+    drone.fwd( 3 );
+    drone.left( 2 );
+    drone.box( blocks.grass ); // create a grass block 
+    drone.up();
+    drone.box( blocks.grass ); // create another grass block
+    drone.down();
+
+...you could simply write ...
+    
+    var drone = new Drone(self).fwd(3).left(2).box(blocks.grass).up().box(blocks.grass).down();
+
+... since each Drone method is also a global function that constructs a drone if none is supplied, you can shorten even further to just...
+    
+    fwd(3).left(2).box(blocks.grass).up().box(blocks.grass).down()
+
+The Drone object uses a [Fluent Interface][fl] to make ScriptCraft scripts more concise and easier to write and read.  Minecraft's in-game command prompt is limited to about 80 characters so chaining drone commands together means more can be done before hitting the command prompt limit. For complex building you should save your commands in a new script file and load it using /js load()
+
+[fl]: http://en.wikipedia.org/wiki/Fluent_interface
+
+### Drone Properties
+
+ * x - The Drone's position along the west-east axis (x increases as you move east)
+ * y - The Drone's position along the vertical axis (y increses as you move up)
+ * z - The Drone's position along the north-south axis (z increases as you move south)
+ * dir - The Drone's direction 0 is east, 1 is south , 2 is west and 3 is north.
+
+### Extending Drone
+
+The Drone object can be easily extended - new buidling recipes/blueprints can be added and can become part of a Drone's chain using the *static* method `Drone.extend`. 
+
+### Drone.extend() static method
+
+Use this method to add new methods (which also become chainable global functions) to the Drone object.
+
+#### Parameters
+
+ * name - The name of the new method e.g. 'pyramid'. 
+ * function - The method body.
+
+Alternatively if you provide just a function as a parameter, then the function name will be used as the new method name. For example the following two approaches are both valid.
+
+#### Example 1 Using name and function as parameters
+
+    // submitted by [edonaldson][edonaldson]
+    var Drone = require('drone'); 
+    Drone.extend('pyramid', function( block,height) { 
+        this.chkpt('pyramid');
+        for ( var i = height; i > 0; i -= 2) {
+            this.box(block, i, 1, i).up().right().fwd();
+        }
+        return this.move('pyramid');      
+    });
+
+#### Example 2 Using just a named function as a parameter
+
+    var Drone = require('drone'); 
+    function pyramid( block,height) { 
+        this.chkpt('pyramid');
+        for ( var i = height; i > 0; i -= 2) {
+            this.box(block, i, 1, i).up().right().fwd();
+        }
+        return this.move('pyramid');      
+    }
+    Drone.extend( pyramid );
+
+Once the method is defined (it can be defined in a new pyramid.js file) it can be used like so...
+
+    var d = new Drone(self);
+    d.pyramid(blocks.brick.stone, 12);
+
+... or simply ...
+
+    pyramid(blocks.brick.stone, 12);
+

+
+### Drone Constants
+
+#### Drone.PLAYER_STAIRS_FACING
+
+An array which can be used when constructing stairs facing in the Drone's direction...
+
+    var d = new Drone(self);
+    d.box(blocks.stairs.oak + ':' + Drone.PLAYER_STAIRS_FACING[d.dir]);
+
+... will construct a single oak stair block facing the drone.
+
+#### Drone.PLAYER_SIGN_FACING
+
+An array which can be used when placing signs so they face in a given direction. This is used internally by the Drone.sign() method. It should also be used for placing any of the following blocks...
+
+ * chest 
+ * ladder
+ * furnace
+ * dispenser
+
+By default, chests, dispensers, signs, ladders and furnaces are placed facing towards the drone so to place a chest facing the Drone just use:
+
+    drone.box( blocks.chest );
+
+To place a chest facing _away_ from the Drone:
+
+    drone.box( blocks.chest + ':' + Drone.PLAYER_SIGN_FACING[(drone.dir + 2) % 4]);
+
+#### Drone.PLAYER_TORCH_FACING
+
+Used when placing torches. By default torches will be placed facing up. If you want to place a torch so that it faces towards the drone:
+
+    drone.box( blocks.torch + ':' + Drone.PLAYER_TORCH_FACING[drone.dir]);
+
+If you want to place a torch so it faces _away_ from the drone:
+
+    drone.box( blocks.torch + ':' + Drone.PLAYER_TORCH_FACING[(drone.dir + 2) % 4]);

+### Drone.times() Method
+
+The `times()` method makes building multiple copies of buildings
+easy. It's possible to create rows or grids of buildings without
+resorting to `for` or `while` loops.
+
+#### Parameters
+
+ * numTimes : The number of times you want to repeat the preceding statements.
+
+#### Limitation
+
+For now, don't use `times()` inside a Drone method implementation &ndash; only use it at the in-game prompt as a short-hand workaround for loops.
+
+#### Example
+
+Say you want to do the same thing over and over. You have a couple of options:
+
+ * You can use a `for` loop &hellip;
+
+    d = new Drone(); for ( var i = 0; i < 4; i++ ) {  d.cottage().right(8); }
+
+While this will fit on the in-game prompt, it's awkward. You need to
+declare a new Drone object first, then write a `for` loop to create the
+4 cottages. It's also error prone &ndash; even the `for` loop is too much
+syntax for what should really be simple.
+
+ * You can use a `while` loop &hellip;
+   
+    d = new Drone(); var i=4; while (i--) { d.cottage().right(8); }
+
+&hellip; which is slightly shorter but still too much syntax. Each of the
+above statements is fine for creating a 1-dimensional array of
+structures. But what if you want to create a 2-dimensional or
+3-dimensional array of structures? Enter the `times()` method.
+
+The `times()` method lets you repeat commands in a chain any number of
+times. So to create 4 cottages in a row you would use the following
+statement:
+
+    cottage().right(8).times(4);
+
+&hellip; which will build a cottage, then move right 8 blocks, then do it
+again 4 times over so that at the end you will have 4 cottages in a
+row. What's more, the `times()` method can be called more than once in
+a chain. So if you wanted to create a *grid* of 20 houses ( 4 x 5 ),
+you would do so using the following statement:
+
+    cottage().right(8).times(4).fwd(8).left(32).times(5);
+
+&hellip; breaking it down &hellip;
+
+ 1. The first 3 calls in the chain ( `cottage()`, `right(8)`, `times(4)` ) build a single row of 4 cottages.
+
+ 2. The last 3 calls in the chain ( `fwd(8)`, `left(32)`, `times(5)` ) move the drone forward 8 then left 32 blocks (4 x 8) to return to the original X coordinate, then everything in the chain is repeated again 5 times so that in the end, we have a grid of 20 cottages, 4 x 5.  Normally this would require a nested loop but the `times()` method does away with the need for loops when repeating builds.
+
+Another example: This statement creates a row of trees 2 by 3:
+
+    oak().right(10).times(2).left(20).fwd(10).times(3)
+
+&hellip; You can see the results below.

+/************************************************************************
+### Drone Movement
+
+Drones can move freely in minecraft's 3-D world. You control the
+Drone's movement using any of the following methods..
+
+ * up()
+ * down()
+ * left()
+ * right()
+ * fwd()
+ * back()
+ * turn()
+
+... Each of these methods takes a single optional parameter
+`numBlocks` - the number of blocks to move in the given direction. If
+no parameter is given, the default is 1.
+
+To change direction use the `turn()` method which also takes a single
+optional parameter (numTurns) - the number of 90 degree turns to
+make. Turns are always clock-wise. If the drone is facing north, then
+drone.turn() will make the turn face east. If the drone is facing east
+then drone.turn(2) will make the drone turn twice so that it is facing
+west.
+
+### Drone Positional Info
+
+ * getLocation() - Returns a native Java Location object for the drone
+
+### Drone Markers
+
+Markers are useful when your Drone has to do a lot of work. You can
+set a check-point and return to the check-point using the move()
+method.  If your drone is about to undertake a lot of work -
+e.g. building a road, skyscraper or forest you should set a
+check-point before doing so if you want your drone to return to its
+current location.
+
+A 'start' checkpoint is automatically created when the Drone is first created.
+
+Markers are created and returned to using the followng two methods...
+
+ * chkpt - Saves the drone's current location so it can be returned to later.
+ * move - moves the drone to a saved location. Alternatively you can provide a Java Location object or x,y,z and direction parameters.
+
+#### Parameters
+
+ * name - the name of the checkpoint to save or return to.
+
+#### Example
+
+    drone.chkpt('town-square');
+    //
+    // the drone can now go off on a long excursion
+    //
+    for ( i = 0; i< 100; i++) {  
+        drone.fwd(12).box(6); 
+    }

+    // return to the point before the excursion

+### Drone Trees methods
+
+ * oak()
+ * spruce()
+ * birch()
+ * jungle()
+
+#### Example
+
+To create 4 trees in a row, point the cross-hairs at the ground then type `/js ` and ...
+
+    up( ).oak( ).right(8 ).spruce( ).right(8 ).birch( ).right(8 ).jungle( );
+
+Trees won't always generate unless the conditions are right. You
+should use the tree methods when the drone is directly above the
+ground. Trees will usually grow if the drone's current location is
+occupied by Air and is directly above an area of grass (That is why
+the `up()` method is called first).
+
+![tree example](img/treeex1.png)
+
+None of the tree methods require parameters. Tree methods will only be
+successful if the tree is placed on grass in a setting where trees can
+grow.
