 * This function is called periodically (as specified by the control frequency).

 * frequency()          returns frequency of simulation.
 * period()             returns period of simulation.
 * duration()           returns duration of simulation.
 * simTicks()           returns elapsed simulation ticks.
 * simTimeInNano()      returns elapsed simulation time in nano seconds.
 * simTimeInMiliSec()   returns elapsed simulation time in miliseconds.
 * simTimeInSec()       returns elapsed simulation time in seconds.
 * overruns()           returns the count of overruns.
 *
 * @return If you return 0, the control will continue to execute. If you return
 * nonzero, the control will abort and stop() function will be called.
