*  Name:
*     chebymap.h

*  Type:
*     C include file.

*  Purpose:
*     Define the interface to the ChebyMap class.

*  Invocation:
*     #include "chebymap.h"

*  Description:
*     This include file defines the interface to the ChebyMap class and
*     provides the type definitions, function prototypes and macros,
*     etc.  needed to use this class.

*  Inheritance:
*     The ChebyMap class inherits from the PolyMap class.
