2.2.0

• Fixed findEventByID on iOS - return null if event is not found (for consistency with Android) #337 by @dstop75

• Fixed android calendar query to catch events that intersect date range but aren't entirely a subset (for consistency with iOS) #333 by @jenniferburch

• Added ability to set timezone on events in iOS (necessary for recurrence expansion to work correctly across daylight savings time transitions) #335 by @LorienHW and @mcarlson

Also includes minor documentation tweaks.
