Stream tables for UI output

[MichaelPesce]

Requested by: @adam-a-a @hunterbarber

Set UI output variables for multiple streams (a stream table) with a single call.
This will remove the need for developers to define each individual state variable for all streams.

• In the construction of the exported output variables, point to state blocks and variables in which the UI can construct a stream table doing the combination of all state blocks (streams)
