Updating Tests and Examples

[FullstackGJJ]

I'm looking through the repo that this port is based off of and it seems like it has a lot of resources that would aid in the documentation for this library. https://github.com/docopt/docopt

I want to upload these examples https://github.com/docopt/docopt/tree/master/examples there is also a lot of python unit tests illustrated here (https://github.com/docopt/docopt/blob/master/test_docopt.py). It would be very beneficial to include these as the python library seems to be more mature.
