Started making chapter 7: Stereoisomerism

Changed table of contents to match the chapter 7 requirements. Started
work on the chapter page.
Added slider tests

Added a test page for sliders: sliderTests.html.
Separated chapter 7 material from tests

Removed chapter 7 material from the playerproto material. Added a link
to the slider tests from the table of contents.
Temporarily removed slider tests from TOC

Adding slider tests to toc-structure.js removed interactivity with the
sliders, so for now sliderTests.html is not part of the test book.
Slider tests are now accessible from TOC

Commented out script tag for the touchSwipe widget. Now interactivity
is possible for sliders on the test page.
Added a button widget and test page

Took Mike's code and ported it to a new widget. Made a few changes to
the code and added a test page for buttons to the table of contents.
first pass at arrows on vectors
Create README.md

1st pass at a readme. I figure it can list some of the references we want developers to be aware of, as well as other things which are on the todo list or need research (and it can include some links as well).
