Paper: A Python-based Post-processing Toolset For Seismic Analyses (S. Brasier, F. Pollard)

Hi, paper builds OK on my PC so I hope this is ready for submission.
> there is no way to regenerate it for interactive use

This is not entirely true in either an interactive session, or between sessions (pickling). Perhaps therefore, it would be sensible to introduce the store and restore capabilities of matplotlib up-front?

I would also recommend explaining why matplotlib's pickle would be a poor choice as a long-term storage format. (i.e. volatile ``__init__`` signature and instance attributes).
