title: Can a subgrid be exported in angular ui-grid
body: <p>I'm using the grid from <a href="http://ui-grid.info/" rel="noreferrer">http://ui-grid.info/</a> in a project.  I've created a hierarchical grid, which works nicely, but when I do an export, it only exports the data from the top-level grid.</p>
  
  <p>This is by design and is standard functionality for the grid, so there's no point in me putting up any example code.  Any example from <a href="http://ui-grid.info/docs/#/tutorial" rel="noreferrer">http://ui-grid.info/docs/#/tutorial</a> will do.</p>
  
  <p>Is there a way to export the subgrid (preferably both the main grid AND the subgrid together as they appear in the grid)?</p>
