Usage of run_difmap on instance

The following command will processing all vis fits file in the directory, and also, there are two modes to choose, clean and modfit. clean is the default mode, and modfit is the mode to do model fitting.

$ python run_difmap.py /the/directory/of/the/file.fits/
# do clean
$ python run_difmap.py /the/directory/of/the/file.fits/ clean
# do modfit
$ python run_difmap.py /the/directory/of/the/file.fits/ modfit
