Detailed Description

This Interface is a new kind of Mapping, called TopologicalMapping, which converts an INPUT TOPOLOGY to an OUTPUT TOPOLOGY (both topologies are of type BaseTopology)

It first initializes the mesh of the output topology from the mesh of the input topology, and it creates the two Index Maps that maintain the correspondence between the indices of their common elements.

Then, at each propagation of topological changes, it translates the topological change events that are propagated from the INPUT topology into specific actions that call element adding or element removal methods on the OUTPUT topology, and it updates the Index Maps.

So, at each time step, the geometrical and adjacency information are consistent in both topologies.
