Detailed Description

A session task will be scheduled to run in background in a timer thread. There can be at most one session task running at a given time (this is ensured by using a timer - which is a single threaded object).

If the session needs to be repeated, it will reschedule an identical session when it finishes to run. This ensure that two session runs are separated by the given interval time.

When run() begins, the state is switched to RUNNING. When run() ends then: If the task is repeated, the state will be switched to SCHEDULED (because a new task was scheduled). Otherwise the state will be switched to either STOPPED (if it was stopped before it could complete) or COMPLETED (if it completed gracefully) This method is used to switch to the desired state and send the appropriate notifications. When entering the method, we check whether the state is STOPPED. If so, we return false - and the SessionTask will stop. Otherwise, we switch the state to the desired value.
