Various Fixes / Improvements about pubplot

This idea of using the font size from the captions as default is really cool. When I started to implement pubplot this was what I had in mind. However, I still could not figure out how to do it...

Right - I think the way to do it would be to put a figure with a caption in the demo page, and print the current font size.

@wwoods I managed to implement it! (see ba529cf)

Previously, my solution to retrieve sizes from the LaTeX document was to store them in LaTeX lengths and then save all these lengths to an auxiliary file. However, I simply could not store the font size when inside a figure caption. So instead, I decided to write all these sizes right to the LaTeX compilation log and use a pattern to be able to detect them. Long story short, now pubplot can detect caption sizes and defaults all sizes to the caption size.

Ah, nifty! Good work :)

PS - any idea when you plan on merging dev -> master and pushing a new release? One of my undergraduates is looking into using this package, and I suspect it would be good to have him working off of the caption sizing / other fixes we've applied in your original repository rather than my fork.

I looked at the issue with Python 2.7 and I am almost convinced it is a bug in matplotlib. Since we are likely the only two using this library at the moment, and you seem to be using Python3, I will merge this right away. I plan to later try to isolate the bug and submit an issue to matplotlib. Hopefully, if they still care about python2, they will fix it.

@wwoods I noticed travis was having trouble to deploy to PyPI but I think I have finally fixed it. You or you undergraduate can now use pip install to use pubplot :-)

Ha, thanks! Very good. Still using pubplot proudly 👍
