// 
// Script to re-upload database data from timestamp X to timestamp Y, also
// known as "annual db initialization procedure"
//
// Input parameters: 
// - database name; typically Calibrations_{subsystem_name} or Geometry_{subsystem_name}. Ex: Calibrations_tpc
// - table name; please check http://www.star.bnl.gov/Browser/STAR/ for the list of your tables
// - flavor name; could be "ofl", "simu" and something else, specific to your subsystem
// - request timestamp; "FROM" timestamp
// - store timestamp; "TO" timestamp
