For Commit: 24c6730 (I only want to merge that commit, not 6 GitHub. User error.)

I updated the readme file. Put in descriptions for the files. Feel free to modify these or put them
under a new file name. I figured they'd be useful in some format, but
I'm not sure if they're best for a README file.  They'll need to be
edited later either way, but it's something useful for now.

I made some minor wording changes to other files while going through them. 

I think we should try meeting up while you're out here in September and smash through some of these issues. Helen is traveling a lot during that time, but she said she'd like to join if possible.
