+*  Name:
+*     mathmap.h
+
+*  Type:
+*     C include file.
+
+*  Purpose:
+*     Define the interface to the MathMap class.
+
+*  Invocation:
+*     #include "mathmap.h"
+
+*  Description:
+*     This include file defines the interface to the MathMap class and
+*     provides the type definitions, function prototypes and macros,
+*     etc.  needed to use this class.
+*
+*     The MathMap class implements Mappings that are specified by a series
+*     of arithmetic expressions that relate output variables to input
+*     variables (and vice versa).
+
+*  Inheritance:
+*     The MathMap class inherits from the Mapping class.
+
+*  Attributes Over-Ridden:
+*     None.
+
+*  New Attributes Defined:
+*     Seed
+*        Random number seed.

+
+*  Feature Test Macros:

+*        If the astCLASS macro is undefined, only public symbols are
+*        made available, otherwise protected symbols (for use in other
+*        class implementations) are defined. This macro also affects
+*        the reporting of error context information, which is only
+*        provided for external calls to the AST library.
