PermMap

Coordinate permutation Mapping

Description:

A PermMap is a Mapping which permutes the order of coordinates, and possibly also changes the number of coordinates, between its input and output.

In addition to permuting the coordinate order, a PermMap may also assign constant values to coordinates. This is useful when the number of coordinates is being increased as it allows fixed values to be assigned to any new ones.
