Opaque datatype that records a start time.
Sets our main struct and passes it to the parent class.
Creates a new timer, and starts timing (i.e. Timer.start is implicitly called for you).
Destroys a timer, freeing associated resources.
If timer has been started but not stopped, obtains the time since the timer was started. If timer has been stopped, obtains the elapsed time between the time it was started and the time it was stopped. The return value is the number of seconds elapsed, including any fractional part. The microseconds out parameter is essentially useless.

Exposes whether the timer is currently active.
Marks an end time, so calls to Timer.elapsed will return the difference between this end time and the start time.
