Fixed z-axis movement bug, removed zPitchComponent and kept zYawComponent
Added camera back (camera angle as main orientation) and removed calculuateGluLookatPoint
Removed commented mouse code, beginning to fix orientating camera rotation (handles mouse rotation flying about an arbitrary axis)
Removed extraneous gluLookat code - unused code
Using glutMotionFunc instead of glutPassiveMotionFunc because easier to control and quit program
Now arrow keys only move camera and oculus object will not call glTranslatef - now mouse chooses direction of flight, oculus looks at surroundings
