Enabled physics.
Gave Bob a gun to shoot with.
Removed the 'MathFunctions' namespace (so all functions that were in it
are just in 'simplicity' now.)
Renamed 'translation' to 'position' and 'transformation' to 'transform'.
Renamed SimpleOpenGLRenderer to OpenGLRenderer.
Fixed the vertex shader to work with stricter implementations (strictly
they cannot take structs as inputs).
Added triangle flipping madness!
