+  Group a number of items across staffs:
+
+  Acknowledge items, put each priority in a separate column.  Put all
+  columns in a horizontal align engraver.  We manufacture two types of
+  elements: the alignment element and the columns.  This is probably
+  more convenient, and I question the use having one without the
+  other.
