/* a basic contents menu plugin by Joel Birch. Demo page to come.
 * okay, so maybe the demo page will never come. Here is a simple usage:
 * $('#mainContentArea h2').contentMenu();
 * This would generate a list of all h2 elements text and link to those h2 elements
 * From there, you should find the other options useful for customising the markup generated
 * and also for changing where the list appears in the source order.
 *
 * updated 4th March 2007 to replace switch with 'object[method]()'
 * so now even less code
 *
 * updated 5th June 2007 to add hooks for enhancements (plugins to this plugin)
 * now stores menu widgets in array, $.cm and each menu widget stores its index as elem.serial expando
