/*
 * This is a prototype script, here are some thoughts
 * for future development : 
 * 
 * 1. The uri building technique in execute() is weak. 
 *    Would be better to call click() on the jQuery obj. 
 *    My initial attempt at that failed.
 * 2. a:contains() selector is case sensitive - should replace.
 * 3. noun_type_clickable should really apply to form 
 *    buttons and other 'clickables'
 * 4. Could also search alt tags of images within anchors to
 *    make those clickable?
