c26cc1a508 Include offending type in precondition failure msg 
Output the type that was incorrect to make it more obvious what the user
is doing wrong without them adding logging.

To avoid string building during lots of vector math, introduced a
private precond module that only builds the strings when an error
occurs. It uses error() to put the resulting error message at the caller
to cpml.

Before:

  lua: ~/cpml/modules/vec2.lua:52: new: Wrong argument type for x (<number> expected)
  lua: ~/cpml/modules/vec2.lua:424: __add: Wrong argument type for right hand operand. (<cpml.vec2> expected)

  example stack traceback:
  	[C]: in function 'assert'
  	~/cpml/modules/vec2.lua:424: in metamethod '__add'
  	test_cpml.lua:32: in main chunk
  	[C]: in ?

After:

  lua: test_cpml.lua:31: new: Wrong argument type for x: string (<number> expected)
  lua: test_cpml.lua:32: __add: Wrong argument type 'string' for right hand operand. (<cpml.vec2> expected)

  example stack traceback:
  	[C]: in function 'error'
  	~/cpml/modules/_private_precond.lua:13: in function 'modules._private_precond.assert'
  	~/cpml/modules/vec2.lua:425: in metamethod '__add'
  	test_cpml.lua:32: in main chunk
  	[C]: in ?

The tracebacks are longer, but the initial error is at the location of
the mistake and the output includes the input type.

a86935a39b Allow ffi.metatype to fail so that "busted" unit tests work 
On Github we run unit tests inside "busted". At the start of each test "busted" does some sort of trick (clearing package.loaded)? Which causes "require" to run again for all lua files. This breaks ffi.metatype with error "cannot change a protected metatable" if it is called twice with a single type name, since this is true global state. To work around this this patch wraps ffi.metatype calls in a xpcall() so that failure is silently ignored.

d9108a198a Make pow work with non-integer exponents. 
As a side effect, it no longer works with non-normalized quaternions.

also moved some vec3 definitions outside their respective function
bodies to speed thing sup and create less garbage

951aea865f Proper fix for the quat.to_axis_angle bug. 
Apparently, I was getting a number so close to -1 (but just under) that
it just printed as -1. Fuck off.
