Scoped mode

[bergie]

NoFlo 0.7 added support for IP Objects that can do flow isolation via scope: noflo/noflo#373 noflo/noflo#162

We should add an option to the MsgFlo runtime that would isolate and identify message-based execution using the scope instead of groups.

This should be an option so that users can switch to scopes with graphs that are fully utilizing the new Process API.

Why should it be an option, shouldn't we just use this always for NoFlo 0.7 ?

[bergie]

Yeah, I realized we may not need a mode for this. With NoFlo 0.7, always post the IP with scope, but also set brackets.

Then at the outport side see whether you still get it from scope, otherwise fall back to topmost bracket.
