@olegz looks good! Did a full build and created several process groups,
processors, input & output ports, funnels, remote process groups, and labels.
Copied & pasted them all over the place, multiple times. Moved in & out of
process groups. Created templates and instantiated them. all appear to work as
expected. Thanks for jumping in and knocking this out - i know it gets tricky!
