Added gl3w to support GL3.2 as well as added a readme so I remember how to use it!
the rendering code now buids, what I need to do to get some simple demo going is:
 - write a gl program to take vertices and normals
 - write a geometry generator to spit out cubes or something simple
 - write a loop to load the model/view/projection matrices then submit the geometry with the new "render" function
