	econtains: function(obj, index, meta, stack) {
	return (obj.textContent \|\| obj.innerText \|\| $(obj).text() \|\| "").toLowerCase() == meta[3].toLowerCase();
	}
	});

jQuery.createPlugin

	// Use: passing in an object representing a jQuery plugin. The object is expected to have
	// a name attribute (your plugin name in string form, e.g. name: "accordion") and an init
	// method. The createPlugin method will take each element in the collection when the
	// plugin method is called and initialize the plugin individually, writing a data object
	// to the element with the same name as the plugin and storing the plugin object for
	// later reference.
