fixing mod order setting, adding in new progress parsing so less error prone, must be used with latest kat version, adding cmd_ags option so that other flags can be passed to kat.run(), like enabling coupling reduction

adding in block selector to loadkatfile and parsecommands, so that it only reads in certain blocks. Fixed factorial code in HG_beam

adding xlim/ylim to map plotting function. Fixing issue in test scripts where it wasn't using the correct kat.ini hopefully
