Roadmap

I'll be adding support for this proposal is implemented. I personally think the matching strategy will lead to a better UX (atomic, no race conditions, faster relay feedback), but currently requires large upfront capital. Matching engine will use sorted sets on top of red-black trees and will be configured as a separate strategy.
