Merge BBUI

https://github.com/jadonk/bone101/tree/master/Support/bone101/UI is a work in progress based on http://jadonk.github.io/Beaglebone-UI/BBUI.html, which is functional. It needs to be re-written in a more readable way. Corrections need to clarify the appropriate voltages to use on the various inputs and properly reflect voltages on the graph.

Start by reading the work-in-progress files under Support/bone101/UI and comparing them with the functional BBUI.html page linked in the issue. Done means the UI is rewritten in a more readable form, the input voltage guidance is clarified, and the graph correctly reflects the voltages.
