Add FAQ

This isn't likely where this document will end up, nor is it styled. But, it's here so that the team can collaborate on the content in once place without having to copy and paste and reformat from another place like Google Docs.

The format is in [Markdown](http://daringfireball.net/projects/markdown/syntax). But, just keep following the same format it's already in and you won't need to worry too much about the syntax. Github has a [nice guide to markdown](https://guides.github.com/features/mastering-markdown/) too.

You can actually feel free to directly edit the file in Github's text editor. Just view the file itself in Github and you'll see an "edit" button. Edit away, github will save the versions for us. 

Feel free to comment away, too, github lets you comment on any line or on the issue or pull request itself. If you need help with using github let me know.
