Add index and new skeleton for next experiment

Add index and new skeleton for next experiment

Adding an index.html which links to and describes the experiments so
far.

Add a skeleton (mostly a bunch of markup) for the next experiment
from the 2013 Hack-A-Way. Intent is to use Dojo and the Dojo
Evergreen support bits to flesh out a new interface for retrieving
patrons and checking items out.

This markup is not complete -- see comments and TODOs.
