CatchmentsResetSearchMaps Method

This will clear the search maps used for finding catchment based on model id or catchment names

If doing intensive operations on the index setter, ItemInt32, it is a good idea to reset the search maps (from a performance point of view). Also, if the search maps some some reason gets out-of-sync, this is a backdoor for resetting the search map.

The search maps will be rebuild whenever one of the methods requiring them is called.
