Adjusted make_roc_curves to now take as many collections as you want.

The cost is now you cannot do offline in it, but that is what the
make_offline_reports is going to be for!
Made laplace smoothing a variable that you can change (since the 1
is actually arbitrary)
Added make_offline_reports, which also writes reports.
Unless, of course, I made a big bad bug. I wouldn't be surprised.
now it (mostly) works -- for some reason labels with "_" characters fail. Dunno why"
Fixed up make_offline_reports.py, though I think now I shall also
include it in SWAP.py as another configurable option -- that makes more
sense!
Incorporated supervised_and_unsupervised -- does both training and test
images
modified so supervised_and_unsupervised ONLY takes training and test images, not any other third category
Now we can do offline in SWAP.py!
typo: supervised goes with training, not test!
make sure I get ALL classifications, dummy!
Merge branch 'master' of https://github.com/drphilmarshall/SpaceWarps
added offline results
fixed the offline running. I think.
