We will add a new group controlcode called "grid".  The definition will be: Indicates that the child items within the group should be organized into a grid, where the horizontal and vertical labels for the grid are determined by parsing the question text.  Each item text SHALL have a single vertical bar (|) that will separate the horizontal label for the item(portion before the vertical bar) from the vertical label for the item(portion after the vertical bar).  The ordering of the labels will be driven by the order in which the items are listed in the group following language conventions (left to right, top to bottom for English, right to left for Hebrew, etc.)  The grid might be fully populated, but could be sparse.  Questions may support different data types and/or different answer choices.
