Editable Tree Grids (Angular)

If you use FlexGrid's childItemsPath to show the data as a tree, the resulting grid will be read-only by default. This happens because every row in a tree is a GroupRow, and group rows are read-only by default. If you want your tree to be editable, handle the loadedRows event to set the isReadOnly property of every row to false.
