title: Is it possible to know if the angular ui-grid is in restore mode?
body: <p>I use the save state feature that allows you to save the current look of the grid and restore it upon returning to the grid. During the restoring process these events will be fired :</p>
  
  <pre><code>gridApi.core.on.filterChanged 
  gridApi.pagination.on.paginationChanged
  gridApi.core.on.sortChanged
  gridApi.selection.on.rowSelectionChanged
  </code></pre>
  
  <p>where I have some logic. I want to block invocation of this code while the restoring process is active.</p>
  
  <p>Is it possible to know if the angular ui-grid is in restore mode?</p>
