[windup-dev] Where to store intermediate data?

[Ondrej Zizka]

A rule, or perhaps during whole execution.
Actually those are 2 different things.

Currently, I need whole runtime scope - for Model metadata.

And also, I was thinking about a rule computing a sum of e.g. JMS queues 
capacities (or anything such).
That would need an iteration, and within iteration, we have VarStack, 
but that's only for WindupVertexFrames, so I was thinking what the user 
has to store data like this, which are not to be reported.
