Initialization

The initialization function sets all of the initial data to be used in the program. The Quadric object qobj is given default value to be modified and used later. this quadric object is sent to specific shape display functions

	qobj = gluNewQuadric();

	gluQuadricOrientation(qobj, GLU_INSIDE);

The final for loops are used to set the initial values of my arrays. These arrays are used for different
