During the events delegation feature handling, it is pretty
common that you need to find some element between the target and
the document which matches some rule. Say in case when you need to
track mouse events over a complicated pile of elements, kinda like
that
var target = event.target;
var targets = [target].concat(target.parents());
var element = targets.first('match', 'my#css.rule');
Would be cool to have some sort of method that will do the
trick
