Examples:
    sportdb cl/teams cl/2012_13/cl                     # import champions league (cl)
    sportdb --create                                   # create database schema

More Examples:
    sportdb                                            # show stats (table counts, table props)
    sportdb -i ../sport.db/db cl/teams cl/2012_13/cl   # import champions league (cl) in db folder
