Detailed Description

Helper processor that merges several input collections into a transient subset collections.

The names and optionally the IDs of the merged collections are stored in collection parameters MergedCollectionNames and MergedCollectionIDs.

Parameters

InputCollections	Name of the input collections
InputCollectionIDs	Optional IDs for input collections - if given, IDs will be added to all objects in merged collections as ext<CollID>()" it is the users responsibility to ensure uniqueness of the IDs across the event ( and that ID != 0 )
