Quiz and Chapter tracking implemented

There are some things we wish could be put into the functions.js rather than HTML but we're limited by the jQM API without a major change in structure that might not ever work as we intend.

The Quiz handles 3 types, checkboxes, radio and text and gives an assessment at the end.

The chapter tracking happens in the state API and is reflected by styled checks on the TOC.

We could use some expert opinions on the formation of the statements.
