basic.cpp:  A basic OpenGL/GLUT program, using no other code or 
   libraries.  Pressing 'b' toggles the sphere's size.

main.cpp: OpenGL/GLUT program using osl/ vector and Axes3d class,
   including mouse handling and lighting.

Building:
  On a Linux machine with the GLUT libraries, you should be able
  to type "make" and get a "main" executable.  Anywhere else,
  you should be able to just compile "main.cpp" to get "main".
