Update the source code for HPC support. Automatically adding nested outputs for the HPC support (should this be available for every support?). Add capability to store the metadata in the Collection DataBase?. Addition of the zcfg2sql to import any existing ZCFG file into the Collection DB. Add the support to invoke a callback (for history purpose) in case a [callback] section contains at least one parameter defined (url). Add support to convert maps and map to JSON (for callback use only by now). Fix some memory leaks (some are still there).
