so it gets rid of Container, which is good.

the UniqueIndex class used to be some kind of encoding of an associative
array into an array, so using a std::map seems appropriate. but i think
it would be even better to remove the UniqueIndex class completely, it
appears that there are still remnants of the old array-mapping in e.g.
UniqueIndexImpl::Insert that seem pointless, also the NextIndex() looks
rather slow, just using map iterators directly would be faster.  just
compute the next key on inserting with something like rbegin()->first +
1 (check for empty() first), that could be a stand-alone function at the
use site.
