[qiyunzhu]

Edited make_names_unique.
Before: Clostridia, Clostridia_1, Clostridia_2, Clostridia_3...
After: Clostridia_1, Clostridia_2, Clostridia_3, Clostridia_4...

Since the original code was too long ago, it won't pass the current Travis test. First error message is Error: HTTPError: 403 Forbidden http://repo.continuum.io/pkgs/pro/linux-64/. There will be a lot more, including non-PEP8 styles.

Also fixed the bug we discussed on Nov. 17, 2017.

@qiyunzhu I want to see how much work it is to migrate this repo to python 3. Might help if you ping Daniel to draw some attention to this task. Hopefully, we than can also work in your updates.

@sjanssen2 I talked with @wasade . He said this 2-to-3 translation effort will be fantastic. Though nobody is currently working on it. Not sure how much work would that be.

Good morning @wasade and @qiyunzhu

It is already done. I just wait for reviews :-)
First step is to update to more recent skbio version PR #28 and if this goes through, another update is awaiting being pushed. I am using the py35 version of tax2tree already for tax-credit.

Best,
Stefan

Just merged #28, thank you @sjanssen2 and @qiyunzhu! I'm excited to see some life come back into this project!
