Description: CLU: dbgen.pl fails to load data files
Reviewed by: nhosoi (Thanks!)
Fix Description: dbgen.pl is hardcoded to look for data files in ../data. Instead, we should allow the user to provide the location to the data files e.g. -l /path/to/data, and we should also use share/brand-ds/data as the default directory.
