Versions of python that tedana works with

[KevinAquino]

Hiya,

I can't seem to find in the documentation but it seems that the latest version works with python 3.6 , and from testing It didn't work with python2.7 -- I was getting importing errors -- I assume the syntax to import modules is slightly different in python 3.

also: duecredit is automatically imported, and so although tedana worked it was popping up an import error -- an easy fix to install but for non-python users might be good to have that as one of the required dependencies.

I know that 3.6 is what we're developing on, and I don't think there are any plans to support 2.7, but it would be a very good idea to document that somewhere. Perhaps we could add information to the README's Installation section, along with a Shields.io badge like to the top with the rest of the badges (as well as to the index page in the docs). If you'd be willing to open a PR with those changes, that would be awesome, but I can do it if not.

Regarding duecredit, I think it's fairly standard to make it an optional dependency, especially since you need to call your scripts in a particular way to generate duecredit bibliographies. The import error is meant to be a warning, and doesn't break anything. We can edit due.py to make the warning more informative though. Perhaps something like "Duecredit not installed. Not able to generate citations, but still functional." We can also document optional dependencies in the README in addition to the required ones already listed.

Thanks @KevinAquino for pointing these out!

I completely agree with @tsalo's suggestion - the badges are great, a little note in the README and maybe in the installation instructions about python 3 only would make this clearer.

I also find the "error" message (it is a warning as Taylor says) for duecredit really annoying. +1000000 to editing that message to make it clearer that it's an optional dependency! ✨
