	//		options described by `add()` to match nodes to actions, or "behaviors".
	//
	//		Added behaviors are applied to the current DOM when .apply() is called,
	//		matching only new nodes found since .apply() was last called.

		// description:
		//		Add the specified behavior to the list of behaviors which will
		//		be applied the next time apply() is called. Calls to add() for
		//		an already existing behavior do not replace the previous rules,
		//		but are instead additive. New nodes which match the rule will
		//		have all add()-ed behaviors applied to them when matched.
		//
		//		The "found" method is a generalized handler that's called as soon
		//		as the node matches the selector. Rules for values that follow also
		//		apply to the "found" key.
		//
		//		The "on*" handlers are attached with `dojo.connect()`, using the
		//		matching node
		//
		//		If the value corresponding to the ID key is a function and not a
		//		list, it's treated as though it was the value of "found".
		//
		//		dojo/behavior.add() can be called any number of times before
		//		the DOM is ready. `dojo/behavior.apply()` is called automatically
		//		by `dojo.addOnLoad`, though can be called to re-apply previously added
		//		behaviors anytime the DOM changes.
		//
		//		There are a variety of formats permitted in the behaviorObject
		//
		// example:
		//		Simple list of properties. "found" is special. "Found" is assumed if
		//		no property object for a given selector, and property is a function.
		//
		//	|	behavior.add({
		//	|		"#id": {
		//	|			"found": function(element){
		//	|				// node match found
		//	|			},
		//	|			"onclick": function(evt){
		//	|				// register onclick handler for found node
		//	|			}
		//	|		},
		// 	|		"#otherid": function(element){
		//	|			// assumes "found" with this syntax
		//	|		}
		//	|	});
		//
		// example:
		//		 If property is a string, a dojo.publish will be issued on the channel:
		//
		//	|	behavior.add({
		//	|		// topic.publish() whenever class="noclick" found on anchors
		//	|		"a.noclick": "/got/newAnchor",
		//	|		"div.wrapper": {
		//	|			"onclick": "/node/wasClicked"
		//	|		}
		//	|	});
		//	|	topic.subscribe("/got/newAnchor", function(node){
		//	|		// handle node finding when dojo/behavior.apply() is called,
		//	|		// provided a newly matched node is found.
		//	|	});
		//
		// example:
		//		Scoping can be accomplished by passing an object as a property to
		//		a connection handle (on*):
		//
		//	|	behavior.add({
		//	|		 	"#id": {
		//	|				// like calling dojo.hitch(foo,"bar"). execute foo.bar() in scope of foo
		//	|				"onmouseenter": { targetObj: foo, targetFunc: "bar" },
		//	|				"onmouseleave": { targetObj: foo, targetFunc: "baz" }
		//	|			}
		//	|	});
		//
		// example:
		//		Behaviors match on CSS3 Selectors, powered by dojo/query. Example selectors:
		//
		//	|	behavior.add({
		//	|		// match all direct descendants
		//	|		"#id4 > *": function(element){
		//	|			// ...
		//	|		},
		//	|
		//	|		// match the first child node that's an element
		//	|		"#id4 > :first-child": { ... },
		//	|
		//	|		// match the last child node that's an element
		//	|		"#id4 > :last-child":  { ... },
		//	|
		//	|		// all elements of type tagname
		//	|		"tagname": {
		//	|			// ...
		//	|		},
		//	|
		//	|		"tagname1 tagname2 tagname3": {
		//	|			// ...
		//	|		},
		//	|
		//	|		".classname": {
		//	|			// ...
