Context Expansion Sometimes Causes Communication Cycles

[cyarp]

Context expansion can sometimes cause communication cycles if nodes are absorbed into a context are from another partition.

Ideally, partitioning would occur after this point but manual partition specification occurs before.

For now, will stop context expansion at nodes in a different partition and will emit a warning.

Possibly may also sometimes scheduling conflicts within a partition

Possibly when FSMs are involved as they contain state and are handled a little differently than standard delays - which should not be absorbed.

Actually, what I was seeing may be related to automated sub-blocking
