Travis + Coveralls

[alvinwan]

@papajohn Can we use Travis and Coveralls? I tried but don't have the permissions to set them up. It should be just a few clicks; I can add the badges afterwards.

@papajohn To add to the wishlist, can we have a wiki too? I think we need a place to document Table and Map features.

I've had bad experience with wikis. They rarely seem to represent the current truth. Feel free to add feature descriptions to readme files.

Ok, I've given permissions to coveralls and travis. @alvinwan can you configure them to your liking?

Sure, that makes sense. I'll add to the README instead then.

Awesome, thanks. I'll add the configs.
