// Date:  10/24/04
// OS dependant: Direct3D
// Desc: Provides a functional set of tools for vectors.  As apart of the
//		 Common Rendering System, the functionality must be similiar to the Direct3d
//		 and OpenGL systems in order to properly relay the data.
// Required headers: 
//	1) C3DTypes.h --
