title: Disable dates older than today in DatePicker plugin
body: <p>Im using <a href="http://www.frequency-decoder.com/2009/09/09/unobtrusive-date-picker-widget-v5" rel="nofollow noreferrer">DatePicker</a> plugin for a project. But I want to Disable dates older than today .(User couldnt select the old dates)
  My js is:</p>
  
  <pre><code>datePickerController.createDatePicker({
  formElements:{"inp1":"d-ds-m-ds-Y"} });
  </code></pre>
  
  <p>In manual :<code>Both methods accept an Object that represents the dates or date ranges to disable.</code>
  I couldnt disable the old days yet with many trial and error. Can you please show me any way to do this?
  Thanks in advance</p>
  
  <p>Edit:</p>
  
  <pre><code>datePickerController.setRangeLow("myElementID",$today);
  
  datePickerController.setRangeHigh("myElementID",$old_dayes);
  </code></pre>
  
  <p>I want to set dynamic date in <code>("myElementID","20081201")</code> .
  Date ranges : <code>$today</code> and <code>$old_days = 'dates older than $today'</code></p>
