Script Only Stack Behaviors and Nesting

They do retain independent values, one set of script locals for each 
instance. For example, if you have two buttons that use the same 
behavior, button 1 will retain its script local values and button 2 will 
retain its own (different) set of values.

The downside to this is I have to get the array in every handler in the behavior script. Not a big deal, but I was trying to be efficient by only having to initialize the values once upon every openStack.

I nailed this down, and it is indeed as someone surmised, that even though the script editor variable watcher indicated that script local variables had the correct values, it was showing me the BEHAVIOR's script local variable values, and NOT those for the STACK, which were in fact still empty (not initialized).

Who knows, maybe I'm going to be the only one in the history of LC to try this, but I just thought I'd toss that out there, in case anyone else gets obscure bugs where a statement ought to work and doesn't.
