first commit biascorrection

[erwinlambert]

First code for the bias correction method in T-S space from Naughten et al.

The biascorr/src/ folder contains relatively clean code and general (plotting) functions, the biascorr/notebooks/ folder contains more messy code to plot examples.

(See if this works:)
Closes #1

@erwinlambert, can you provide me with the following that would help me review this?

What packages do I need to run the scripts and notebook?

Is there some way for me to usefully run the code? If not, that's fine. I can just inspect it.

[erwinlambert]

@xylar , I was actually just writing up an email to suggest Nico to review the code, as we'll need to exchange and collaborate mostly.

Still, if you do want to review, the list of packages is:

• xarray
• numpy
• matplotlib
• cmocean
• whatever is necessary to run notebooks (ipython?)

However, the code won't run without the data I'm afraid, which is a whole bunch of large cmip output files

@erwinlambert, I just invited @nicolasjourdain to join the the repo. I think it's best for him to review. This looks good to me at a quick glance.

@erwinlambert, I think this looks good. The code is clean and will be easy to incorporate into a package in the near future so it's easier to share code between parts of our project.

Great, I will see whether @nicolasjourdain wants to have a look as well. Otherwise I'll merge the code as a starting point
