Help message is uninformative

[kmadathil]

Side effect of the new api - need to make the right help message come up too

$ scripts/sanskrit_parser vakya --help
unable to import 'smart_open.gcs', disabling that module
usage: sanskrit_parser [-h] [--debug] {sandhi,vakya,tags}

How about using a standard package like click, which appears to support nesting commands ?

[kmadathil]

Yes, we need a better package than argparse. click looks like a good option. I've committed a workaround for now, but this is another one which needs a good solution.

So this is a 2nd Sanskrit parser additional to Huet's?
