+/*****************************************************************************
+	class CSimpleDividedView
+	Simplest divided view.
+ 
+ ### Standard usage:
+  In Constructor, create the CSimpleDividedView from a template,
+  set the IDs and min size of subviews
+  
+  It should be in the same level of hierarchy as the views it manages.
+  It does not do any drawing
+  
+  It broadcasts msg_SubviewChangedSize after a successful drag. Hook it up
+  to your window manually (outside the RidL resource), because it is not a
+  LControl subclass. Do this only if you need to do something in response to
+  resize. For example, recalc the GrayBevelView.
+  
+  timm has a more sophisticated class, divview.cp, which takes car of resizing
