> After a false start as described in attached, I implement a removeAllKeys call to KVStore that is capable of deleting all keys that match a particular class' index.  The implementation in LevelDB performs a delete based on each key, as elements in LevelDB are indexed, and the implementation in InMemoryStore performs a scan and conditional remove, as elements in InMemoryStore are not indexed.
