Now, LitScene allows for simple lighting. (Shadows still to come).
Ambient, specular, and diffuse lighting available and each mesh's
vertex can define a material that defines its reflectivity. An
example scene was added to the MyApplication as the scene for the
6 button.
Builtin general structure created. Added a builtin::BasicScene
class for quick general testing of the engine on different systems.
The builtin::BasicScene class greatly reduces the amount of code
needed to be handled by the developer by offering a pre-made way
to handle it. It even includes pre-made shaders!
