 *	Desc: SimsGraphics object.  this object contains the main OpenGL code to 
 *	load files, display objects.  It keeps track of every graphical object and 
 *	draws them every 30th of a second (or whatever time interval we decide).  It
 *	also performs operations that the GUI requires (transforming pixel 
 *	coordinates to world coordinates, moving the camera around, etc)
