Kronos copier

A script to bulk-load test data into Kronos, and a script to copy data between streams.

NOTE: I think there's a subtle bug in the stream_comparator that forgets the last timestamp up for comparison (after the loop exits).  If I insert 3000 events, the comparator says the stream total is 2999, for example.
Ah gotcha.  Can we do this in v2?  My guess is for our migration we won't need it?
