Two models and a texture for them
Enemies Added to code

Added an enemy .h and .cpp file, added some of the stuff to the
materials and game loop. I need to still add enemy logic, I just want it
to compile and have an enemy appear.
Fixed model load crash

No longer crashes loading enemy model
Enemies are spawning

Enemies correctly initialize and spawn, it's just they don't go away.
Fix enemy model normals
newer space invader model with correct normals
Fix enemy crashing game (removed second unregistergameobject)
