Detailed Description

Implements a Handle-sequence index as an RB-tree (C++ map) That is, given a HandleSeq, it will return a (single) Handle associated with that HandleSeq. This map is in the "opposite" direction from the HandleIndex.

Todo:

Notice that it this wastes a fair amount of RAM by storing a copy of a HandleSeq — it could save a fair amount of space by storing a pointer to the HandleSeq that is in the Link already (at the cost of some fragility in Link deletion). Alternately, we could use a "HandleSeq cache", analogous to a string cache, to ensure only one copy of a HandleSeq per system... XXX FixMe!
