/**
 * launchMig.php -- help script
 *
 * This program is called from the: migrateData.php application as an AJAX event - the sole purpose of this script
 * is to unpack the POST data from the AJAX request, and build a migration-request event broker payload.
 *
 * Next, we instantiate a new broker client to the migration broker and publish the migration event request - the
 * output from the script is in the broker payload returned by the migration broker -- if all was successful, we'll
 * output (for formatted display) the migration report -- else, we'll display the diagnostic messages.
