Is python3 required?

[rsharris]

I was trying to run this using python2 (because I didn't know any better). I get an exception from str.maketrans() on kmers.py. In python2 (apparently) string objects don't have a maketrans method, whereas (I guess) in python3 they do.

If the package isn't intended to support python2, it would be nice to say that in the readme.

That's interesting : I've only ever used python2.7, so I believe DiscoverY should work fine with python2. Let me look into this and let you know.

Discussed this with Tasha. She achieved some speedups by converting to python3. Backward compatibility with python2 wasn't maintained. Probably reasonable since python2 wil lbe a problem for all of us after Jan/1/2020.

The readme should be modified to reflect that, though.

For my present effort, which is just running the example so I know how to run this, I've just modified my copy of the source code so that it runs under python2. The only change I had to make was that use of maketrans.
