Python 2 support

[agitter]

It looks like only Python 3 is currently supported due to the way the optional arguments are provided to the plot function. Is that correct?

[afrendeiro]

True. Your fork works fine though. Thanks!

[agitter]

Thanks for commenting. I didn't yet examine the consequences of re-ordering the arguments in my fork. Does any other code make use of these optional arguments and need to be changed to be consistent?

Forgive my delay, for some reason I wasn't receiving notifications for this repo.

The package was developed mainly with python 3 in mind, that's correct.

I will take a look at the changes and get back to you asap.
