Detailed Description

Implements a Handle index array of RB-trees (C++ set) Given a Handle, this returns the incoming set of that handle.

Todo:

The iterator is NOT thread-safe against the insertion or removal of atoms! Either inserting or removing an atom will cause the iterator references to be freed, leading to mystery crashes!

The const UnorderedHandleSet& returned by the getIncomingSet() method will also become invalid if an atom is inserted or deleted (for that particular IncomingSet).
