compute_widths only looks at models in main madgraph directory

[Alex Sherman]

When attempting to use compute_widths, even if a model import has been specified to another directory, there will be an error thrown if a copy of that model is not in the main madgraph/models directory. Debug file is attached, I had created a copy of a UFO model that I knew was NOT in my MadGraph/MG5_aMC_v2_2_3/models/ directory.

Also, once you put a copy in the MG5_aMC_v2_2_3/ directory, it will still save the param_card.dat to the originally specified model import location, not the one in the MG5_aMC_v2_2_3/ directory, even though it requires this one to function.

Thanks a lot,

Here is the fix:

             with misc.MuteLogger(['madgraph'], ['INFO']):
                 model = import_ufo.import_model(model name, decay=True)

Cheers,
