title: How to limit the available Date ranges with the com.google.gwt.user.datepicker.client.DateBox
body: <p>I need to limit what <code>Dates</code> a user can pick from the <code>com.google.gwt.user.datepicker.client.DateBox</code>.</p>
  
  <p>I can't seem to figure out how to limit the min <code>Date</code> so they can't pick past dates.</p>
  
  <p>If I can't do this with <code>com.google.gwt.user.datepicker.client.DateBox</code> is there an alternative <code>DateBox</code> widget that will allow me this kind of flexibility?</p>
