This work is based on discussion and etherpadding (is that a verb) on
April 14th between Deb, Greg, Karen, Will, and Chris.
It was an epic collaborative sprint.
* fixes some typos
* tweaks some language issues that occured because I took Chris'
stuff out of the context of the original READMEish structure
* ditches installation for deploymenthowto and hackinghowto
use, what their function is, and urls for library documentation
* adds a forward chapter which talks about the documentation
* adds an installation stub
* adds a software stack chapter that covers what libraries are in
* adds a design decisions chapter which covers why we chose the
libraries and architecture
