# This script uses "history" versions of dataSnapshot and SchemaGenerator (via genTester)
# java classes to do the INITIAL load of a history database based on regular dataSnapShot
# files (assumed to be 'clean') from an existing non-history database.
# Steps:
# 1) Make sure the db is empty: clear out any existing data and schema.
# 2) rebuild the schema (using the SchemaGenerator4Hist)
# 3) reload data from the passed-in datafiles (which must found in the dataSnapShots directory and
# contain a json view of the db data).
