# 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).
