* Handles clicking **outside** of a specified set of elements, then fires an action.

* **Note**: Actually, the action is executed upon `mousedown`, not `click`. It prevents

* properly.
*
* @param options Configuration options.
* @param options.emitter The emitter to which this behavior should be added.
* @param options.activator Function returning a `Boolean`, to determine whether the handler is active.
* @param options.contextElements Array of HTML elements or a callback returning an array of HTML elements
* that determine the scope of the handler. Clicking any of them or their descendants will **not** fire the callback.
* @param options.callback An action executed by the handler.
* @param options.listenerOptions Additional options for the listener (like priority).
