[Boa Constr] Setting up sizers in 0.2.6

[Allen B. <al...@vr...>]

First, fair warning I am a newbie to using boa constructor.  I just got 
started and I see how to use the designer to add standard widgets but I 
can not seem to figure out how to use the sizer tools.

I have deciphered that sizers have to be added to the "Sizers" window 
pane instead of the designer window.  But once I have a new sizer object 
I don't see how to add objects to the sizer.

I know this is a very new feature, but is there any pre-release 
documentation anywhere that I can look at?

Thanks,
Allen
