- Previous Bug detected
	- was due to randomChurn generator killing the source node
      & then failing the assertion in preKillNode [mobilityTimer]
      (oldTerminalCount-1 == terminalCount)
    => we cannot use the randomChurn generator for now [until
       then bug is resolved]
- MeasurementTime parameter is added to the configuration file

TODO
    - Don't accept the leave requests when they are from the leaf nodes
    	  [Remove them from your children set]
	- Plug in the rescue mode call at handleSwitchToRescueMode
    - Think about the deadline segments & sequencing operation
- Ready for the simulation phase 
	- at least startup time & transfer delay can be estimated correctly
	- need to define the sequencing & deadline segment scheduling
		for packet continuity index
- Leaf node's request for leave is now accepted correctly
	- No replacement found
- TODO
	- Packet continuity index => deadline segment scheduling & sequencing
	- Optimizing the #of control messages used
	- Optimizing the height of the tree
	- Need some more optimizations for the improving the characteristics
