/**
* Reads a Grid constructed using flux:grid, returning an array of
* defined rows and columns along with any content areas.
*
* Note about specific implementations:
*
* * EXT:fluidpages uses the Grid to render a BackendLayout on TYPO3 6.0 and above
* * EXT:flux uses the Grid to render content areas inside content elements
* registered with Flux
*
* But your custom extension is of course allowed to use the Grid for any
* purpose. You can even read the Grid from - for example - the currently
* selected page template to know exactly how the BackendLayout looks.
*
* @param ViewContext $viewContext
* @param string $gridName
