[Bf-committers] Group indentification code

[David Bryant]

 I'm writing a feature that will enable Groups to toggle 
visible/invisible.Interface is finished. I have finished code that will 
enable you to select an object in a group and then hide the whole Group that 
that particular object is in.But, I need to write a function that 
"remembers" which Groups are hid so that when other Groups are hid 
simultaneously,when an individual Group's toggle is toggled to visible, it 
will unhide that specific Group only and not the others(each Group has it's 
own visible/invisible toggle button).

My question is:
How are Groups individually identified in the source code?

Once I can "clearly" grasp that answer the feature will be finished.

Hope someone can help.
