"""This code significantly adds to the capabilities of the Django Management control panel for Troggle data.
In particular, it enables JSON export of any data with 'export_as_json'
and configures the search fields to be used within the control panel.

What is the search path for the css and js inclusions  in the Media subclasses though ?!

The page looks for /static/jquery/jquery.min.js
