Wait - I see what you're asking... how are we going to use this to index our data? Well, we already use "id" to index into rather large maps (yes, regular std::map) to get at this data and we haven't seen that showing up in our timing.... so I'm not super worried about it.

Yep, super sparse... So some some sort of hash map (probably
unordered_map) of unique_id->object (but could be unique_id->id....
don't know which one is best yet).
