1. Made sure we treat properly option expiration dates before Feb 2015 and after. Added tests.
2. Refactored expiration delisting, assignments/option exercise to happen in the end of the date, not MOC orders in the beginning of the day. Regression test.
3. Refactored option exercise model to generate proper fills on assignments/option. Those fills are reflected correctly in margins, in stats and correspond to IB model. Still need to run IB real-life live tests.
4. Refactored option symbol related functions into separate module (OptionSymbol.cs)
5. Made sure OnAssignmentEvent arrived to the user algo in regression test. Do we need OnExercise event? Not sure.
6. Tested end-to-end Ray's current code (covered call strat) to see short option legs expire worthless, and stats updated.
