+    Demo - Separator Elements
+
+    Shows usage of both Horizontal and Vertical Separator Elements
+    Vertical Separators are placed BETWEEN 2 elements ON the same row.  These work well when one
+        of the elements is a Column or the element spans several rows
+
+    Horizontal separators are placed BETWEEN 2 rows.  They will occupy the entire span of the row they
+        are located on. If that row is constrained within a container, then it will spand the widget of
+        the container.
