Move the analytics include beneath the head_js include

Move the analytics include beneath the head_js include.
Added documentation for the debounce JavaScript helper function.  Also reorganized the js-component names alphabetically in the controller, helper, and routes files.
Updated documentation copy for the example to describe the debounce function instead of the old copy for proximity loader.
