/*
   Behaviour v1.1 by Ben Nolan, June 2005. Based largely on the work
   of Simon Willison (see comments by Simon below).

   Description:
    
     Uses css selectors to apply javascript behaviours to enable
     unobtrusive javascript in html documents.

   Usage:   
   
     var myRules = {
       'div' : function(element){
        	element.onclick = function() {
			alert('foo');
		}
       },

       '#somediv':  function(element){
        	element.onclick = function() {
			alert('bar');  
		}
       }
     };

     Behaviour.register(myRules);
  
  // Call Behaviour.apply() to re-apply the rules (if you
  // update the dom, etc).
