Detailed Description

Overall Flow: rewrite switchboxes to assign unassigned connections, ensure this can be done concurrently ( by different threads)

1. Goal is to rewrite all flows in the device into switchboxes + shim-mux
2. multiple passes of the rewrite pattern rewriting streamswitch configurations to routes
3. rewrite flows to stream-switches using 'weights' from analysis pass.
4. check a region is legal
5. rewrite stream-switches (within a bounding box) back to flows
