 UnitMap 
   Unit (null) Mapping  
      
Description: 
 A UnitMap is a unit (null) 
Mapping
that has no effect on the coordinates supplied to it. They are simply copied. This can
be useful if a Mapping is required (e.g. to pass to another function) but you do
not want it to have any effect. The 
Nin and 
Nout attributes of a UnitMap are
always equal and are specified when it is created.  
Constructor Function 
  Inheritance  
 The UnitMap class inherits from the Mapping class.  
 
Attributes  
 The UnitMap class does not define any new attributes beyond those
which are applicable to all Mappings.  
  Functions  
 The UnitMap class does not
define any new functions beyond those which are applicable to all Mappings.
