Update python docs

[jmcarp]

Warning: this is an opinionated patch! I deemphasized doctest (which isn't a testing framework and shouldn't be treated as such) and moved pytest to the top. I also deleted most of the code examples, since they were hard to find--and, more importantly, because many excellent examples already exist, often on the first page of the official docs.

• Add testing libraries
• Add testing resources
• Remove standalone code examples, since they're hard to find; prefer
  linking to existing examples, of which there are many

[Resolves #20]

I don't object to jettisoning the examples or the reordering, but I do object to removing my nose tips. 😛 Unless they can be reworked to apply to pytest.... But I have barely ever used pytest, so I wouldn't know.

@arowla: what do you think about moving the nose tips to a separate file? I was also trying to get the main python page to fit inside a screen or two. If linking to third-party guides won't cut it, I think it would make sense to add nested pages for examples on specific test runners.

Updated. Not sure why travis is failing, or even enabled.

[mbland]

Oh, I enabled a bunch of repos before adding .travis.yml files. My bad. I'll start adding them.

Since Travis is just failing on a technicality, going to merge.
