CMORmeal: omission tracking

[ilaflott]

if the tool can't process a file, then we've gotta track that somewhere! i.e. should work like the following pseudocode:

for file in files:
    try:
        cmorize(file)
    except:
        write_to_omission_log(file)

I think implementing this makes more sense when we do bulk tests.
