title: Resetting SlickGrid for new data
body: <p>I have a SlickGrid in which the user can choose various datasets. Thus the schema can change. So when the user selects a new dataset, I need to either delete the SlickGrid and start over, or clear the existing one.</p>
  
  <p>What is the proper approach? Should I just delete the DOM node? I have looked through the API and cannot find any grid level calls that appears to accomplish what I am looking to do.</p>
  
  <p>thanks</p>
