/*  Migrated the main.js file and contents in the index page to here!

In doing so we can properly separate different scripts by activity, making an easy to manage heirarchy.

For example, the window.onload function is a "main" process, it does more than just the cookies process.

Similarily the instantz javascript model class is a model for all instantz website activities, not just cookies.

So they too have been migrated to this main.js file.

This leaves the cookies.js with just the javascript cookie handler, as it should be.
