Base class for objects that can get the focus.

The focus is used to designate an element that will receive keyboard events.

canGrabFocus	Return true if the element can be focused.
focusController	Return the focus controller for this element.
focusIndex	An integer used to sort focusables in the focus ring. A negative value means that the element can not be focused.

Blur	Tell the element to release the focus.
Focus	Attempt to give the focus to this element.

HandleEvent	Handle an event, most often by executing the callbacks associated with the event.
HasBubbleHandlers	Return true if event handlers for the event propagation bubble up phase have been attached on this object.
HasCaptureHandlers	Return true if event handlers for the event propagation capture phase have been attached on this object.
OnLostCapture	Called when the element loses the capture. Will be removed in a future version.
RegisterCallback	Add an event handler on the instance. If the handler has already been registered on the same phase (capture or bubbling), this will have no effect.
UnregisterCallback	Remove callback from the instance.
