Drop `numpydoc` style docstrings throughout?

[goodboy]

I'm thinking moving to standard sphinx markup is most desirable? See here: https://github.com/rtfd/readthedocs.org/issues/995 Currently it's as simple as adding numpydoc to the reqs file to get it working with rtd.

I'm just not sure if everyone else gets their pants as messy thinking about numpy....

Opinions?

Or not... Apparently now everyone's cool with numpy docs...
