Quick step/scrub/switch logging
- state transition happening due to Home and back is handled by
specifying src target as 'from' container and dst target as the 'to'
container
- Source and Destination container shows FROM and TO state for SWIPE/FLING
- event.isStateChange = true indicates that an action resulted in
state transition
- Elapsed container millis is the screen time on the source container
