- Remove unused `OptionChainUniverseDataCollectionAggregatorEnumerator`
- Refactor `BaseDataCollectionAggregatorEnumerator` and
`OptionChainUniverseDataCollectionEnumerator` to avoid emitting invalid
data points
- Updating regression tests statistics
- Adding unit test
- Fix bug in live mode custom universe,
`BaseDataCollectionAggregatorEnumerator` returning false was causing the
subscription to be removed completely
- Adding unit test
This places all security subscriptions within a universes
Subscriptions generated via calls to AddSecurity are place in a UserDefinedUniverse
UserDefinedUniverse will serve up a predetermined list of symbols on a requested interval
LiveTradingDataFeed - reworked custom enumerators to use RefreshEnumerator as wrapper for rate limitting
Maybe an event handler isn't the best way to do this, possibly
initializing the data feed with the universe selection instance
would be better, leaving as is for now
