Finally got a 3D cube to be rendered. While doing it, fixed a
bug in MeshFactory that caused it to allocate the incorrect amount
of memory for each mesh.
Now using GLFW3 instead of the custom window class. This library
looks like it will make development much simpler and will make it
so that I am less worried about my windows code breaking. Currently
setup the http://antongerdelan.net/opengl/hellotriangle.html
tutorial in the MySimpleScene. Will probably create another scene
file to try to get the object oriented stuff working.
