Removed redundant getter methods in Vector3.
Added basic display, reshape, and idle callbacks.
Added basic program with major bug.

I can't yet ascertain what is causing the bug, but running the program in its
current state causes X11 to hang until I can force a VT to show so that I can
kill the program.  GDB shows a backtrace originating within gettimeofday
that traces through freeglut up to my call of glutMainLoop.
Added a makefile for the project proper.
Added fundamental build instructions.
Added empty header for RenderObject class.
Fixed a compiler error.
Added GlutCallbacks header file listing GLUT callback functions.
