00032 // Description: This file contains the class definition for 
00033 // CrdTransf.h. CrdTransf provides the abstraction of a frame 
00034 // coordinate transformation. It is an abstract base class and 
00035 // thus no objects of  it's type can be instatiated. It has pure 
00036 // virtual functions which  must be implemented in it's derived classes.
