Collect and review Rob's "circuit scheduling subsystem refactoring" patch
Rob recently refactored the circuit scheduling subsystem to make it easier to add new schedulers. The current RR and EWMA schedulers have been ported as new scheduling modules. We should review his code to determine if we'd like to move forward with the design.
The code is available in branch "schedule-refactor" at: git://github.com/robgjansen/torclone.git
