/*****************************************************************************
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
