Remove LayoutManager.initialize() method?

[Glen Mazza]

Team,

Anyone have a problem if I remove the initialize() method from the 
LayoutManager interface (and assorted related code from 
AbstractLayoutManager), by having the eight LM's currently using it 
initialize themselves internally instead?

Currently, for those 8 LM's using external initialization (i.e., 
LM.initialize()), it is done immediately after the ParentLM is set for 
the LM in AbstractLayoutManager.addChildLM().  So, at a minimum, I think 
I can equivalently do this by having each class call initialize() within 
an overridden setParent() implementation.  However, for most of the 
eight it appears I can just call initialize() from the class' 
constructor without needing a setParent() override.

This change will not prohibit specific LM's with unique requirements 
from having a public initialize() method, if ever needed, it would just 
require that a specific class variable be used instead of the generic 
LayoutManager interface variable (i.e., for WidgetLayoutManager wlm, 
call wlm.initialize() instead of LM.initialize().)

Thanks,
Glen
