title: How to clear all data is jsGrid?
body: <p>There are many answers on how to clear the data from the similarly-named <a href="http://www.trirand.com/blog/?page_id=15" rel="nofollow noreferrer">jqGrid</a>, but I can't find any way to clear data from <a href="http://js-grid.com" rel="nofollow noreferrer">jsGrid</a>. I just want to delete all rows and reset the grid to its default, with no rows.</p>
  
  <p>I do see a <a href="http://js-grid.com/demos/" rel="nofollow noreferrer">Batch Delete method here</a>, but it works with checkboxes and conditionals and I'm not seeing how to simply delete all rows unconditionally.</p>
