Hi,

Improve handling of some corner cases that are not used by current topology
designs, but can be crafted within the rules of a topology file.

For example branching topologies, where a single input routed to multiple
output endpoints. The already configured part of the graph places constraint
on how the new branch can be configured.

Handling of process modules also updated to be able to 'guess' what
parameters can be changed by the module and allow flexible operation.

Regards,
Peter
