-*+
-* Name:
-* unitnormmap.h
-
-* Type:
-* C include file.
-
-* Purpose:
-* Define the interface to the UnitNormMap class.
-
-* Invocation:
-* #include "unitnormmap.h"
-
-* Description:
-* This include file defines the interface to the UnitNormMap class and
-* provides the type definitions, function prototypes and macros,
-* etc. needed to use this class.
-*
-* A UnitNormMap is a Mapping which, in the forward direction,
-* subtracts the specified centre and then transforms the resulting vector
-* to a unit vector and the vector norm.
-* The forward direction outputs one more coordinate than is input.
-*
-* The inverse transformation of a UnitNormMap multiplies each component
-* of the provided vector by the provided norm and adds the specified centre.
-* The forward direction outputs one fewer coordinate than is input.
-*
-* Example: if centre = [1, -1] then [5, 2] transforms to [4, 3] after subtracting the centre;
-* the norm is 5, so the output is [0.8, 0.6, 5]
-*
-* UnitNormMap is intended for applying radially symmetric distortions, as follows:
-* - apply a UnitNormMap to produce a unit vector and norm (radius)
-* - apply some one-dimensional mapping to the norm (radius), while passing the unit vector unchanged
-* - apply the same UnitNormMap in the inverse direction to produce the result
-*
-
-* Inheritance:
-* The UnitNormMap class inherits from the Mapping class.
-
-* Attributes Over-Ridden:
-* None.
-
-* New Attributes Defined:
-* None.
-
-* Methods Over-Ridden:
-* Public:
-* None.
-*
-* Protected:
-* ClearAttrib
-* Clear an attribute value for a UnitNormMap.
-* GetAttrib
-* Get an attribute value for a UnitNormMap.
-* SetAttrib
-* Set an attribute value for a UnitNormMap.
-* TestAttrib
-* Test if an attribute value has been set for a UnitNormMap.
-* astMapMerge
-* Simplify a sequence of Mappings containing a UnitNormMap.
-* astTransform
-* Apply a UnitNormMap to transform a set of points.
-
-* New Methods Defined:
-* Public:
-* None.
-*
-* Protected:
-* None.
-
-* Other Class Functions:
-* Public:
-* astIsAUnitNormMap
-* Test class membership.
-* astUnitNormMap
-* Create a UnitNormMap.
-*
-* Protected:
-* astCheckUnitNormMap
-* Validate class membership.
-* astInitUnitNormMap
-* Initialise a UnitNormMap.
-* astInitUnitNormMapVtab
-* Initialise the virtual function table for the UnitNormMap class.
-* astLoadUnitNormMap
-* Load a UnitNormMap.
-
-* Macros:
-* None.
-
-* Type Definitions:
-* Public:
-* AstUnitNormMap
-* UnitNormMap object type.
-*
-* Protected:
-* AstUnitNormMapVtab
-* UnitNormMap virtual function table type.
-
-* Feature Test Macros:
-* astCLASS
-* 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.
