/**
* A simulation consists of a number of motes and mote types.
*
*
* The motes in the simulation are ticked one by one in a simulation loop. When
* all motes have been ticked once, the simulation time is updated and then the
* simulation sleeps for some specified delay time. Any tick observers are also
* notified at this time.
*
*
* When observing the simulation itself, the simulation state, added or deleted
* motes etc. are observed, as opposed to individual mote changes. Changes of
* individual motes should instead be observed via corresponding mote
* interfaces.
