* Name:
* normmap.h
* Type:
* C include file.
* Purpose:
* Define the interface to the NormMap class.
* Invocation:
* #include "normmap.h"
* Description:
* This include file defines the interface to the NormMap class and
* provides the type definitions, function prototypes and macros,
* etc. needed to use this class.
*
* The NormMap class implements Mappings which use a Frame to
* normalise the input axis values.
* Inheritance:
* The NormMap class inherits from the Mapping class.
