+    Simple template window that saves position.
+
+    Rather than starting in the middle of the screen, this code will save the position the window was in when it last exited.
+
+    To pull this off it's going to be.... super.....?hard?
+    No... of course it's going to be... SIMPLE
+
+    There is one added line of code.  When the user attempts to close the window, that's when the position is saved.
+    When the program starts, it reads the previously saved position as part of the window creation.  User Settings APIs rock!
