The default behaviour of Cloudlets make it log information about movements it 
does between resources. It may cause unnecessary consumption of heap space, 
especially because most simulations do not require such movement information, 
as it can be tracked by the broker.

Therefore, the default behaviour of Cloudlets should be not logging movement, 
and if users want to log, they can use the alternative constructor with the 
extra boolean record parameter (set to true for enabling the record).
