// *****************************************************************************
//
// CLASS DESCRIPTION (MFloatPoint)
//
//	This class provides an implementation of a point in float.  Numerous 
//	convienence operators are provided to help with the manipulation of 
//	points. This includes operators that work with the MFloatVector and 
//	MFloatMatrix classes.
