//The Timer class // The instance of this class is created in the qBot object under the name 'timer'
//The methods that are available to call from this instance are:
//timer.setTimer : Creates a new timer with the given interval (miliseconds).
// Optionally set dalay or a limited repeat value.
//timer.checkTimer : Gives true if called at the time of the interval.
//timer.clearTimer : Deletes the timer permanently. No way to get the same timer back.
//timer.activateTimer : Sets the status of a deactivated timer to active.
//timer.deactivateTimer : Deactivates a timer. Deactivated timers will never give true.
