// glue it to an element.  Each element then gets it's own instance of the behavior and any
// methods called onxxx are bound to the relevent event.

// Usage:
// 
// var MyBehavior = Behavior.create({
//   onmouseover : function() { this.element.addClassName('bong') }

//

// If you need to pass additional values to initialize use:
//
// Event.addBehavior({ 'a.rollover' : MyBehavior(10, { thing : 15 }) })
//
// You can also use the attach() method.  If you specify extra arguments to attach they get passed to initialize.
//
// MyBehavior.attach(el, values, to, init);
//
// Finally, the rawest method is using the new constructor normally:
// var draggable = new Draggable(element, init, vals);
//
// Each behaviour has a collection of all its instances in Behavior.instances
