[cells-devel] Question about families and kids

[Josip Gracin]

Hello!

Could somebody please give me a hint why are the families and kids part 
of Cells?  Obviously, I ask this because I don't really understand their 
purpose.  Is this "family" functionality only a bunch of convenience 
functions for organizing objects in a tree structure or is there some 
more profound reason for its being a part of Cells.

Thanks!
