I've attached a pdf containing high level design and API contracts for
scheduler. This is first draft. Please review and let me know your suggestions.
On a high level, here's the proposal:
1) Support for Abstract Scheduler - More so like a scheduler execution engine
specification. Quartz Scheduler will extend the Abstract Scheduler. There can
be other implementations to the abstract scheduler too (akka or something else)
