title: Is it possible to disable the autoopen function of the angular ui datepicker?
body: <p>I don't like the autoopen function of the angular ui datepicker  (the automatic display of the calendar when the control gets focus). What I want is to click a button to open the datepicker when needed, but otherwise leave the calendar closed. Is this possible with the angular ui datepicker? I didn't see any option in the documentation. </p>
