/** Example 009 Mesh Viewer
This tutorial show how to create a more complex application with the engine.
We construct a simple mesh viewer using the user interface API and the
scene management of Irrlicht. The tutorial show how to create and use Buttons,
Windows, Toolbars, Menus, ComboBoxes, Tabcontrols, Editboxes, Images,
MessageBoxes, SkyBoxes, and how to parse XML files with the integrated XML
reader of the engine.
We start like in most other tutorials: Include all nesessary header files, add
a comment to let the engine be linked with the right .lib file in Visual
Studio, and declare some global variables. We also add two 'using namespace'
statements, so we do not need to write the whole names of all classes. In this
tutorial, we use a lot stuff from the gui namespace.
