JS Experiments

[bengolder]

This branch is a place to experiment with javascript functionality. It should not cause any significant interference to files other than templates/template_prototyping.html, other than doing basic clean up or adding class names to template includes.

We should merge this branch when the experiments are complete and if we like their example implementation. Please feel free to propose specific cases that should be tested.

What is being worked on here:

• [x] Conditional Field Display (#110)
• [x] One way data binding (#117, #118)
• [ ] Front end form validation(#130, #126, #123)

[bengolder]

Added a basic data binding example, in a very similar manner to the conditional display. Note that the receiving element doesn't change until the originating field loses focus.
