/*
Timer class, uses getTimer for timing
timerInstance = new Timer( [ startCountDown ] );
- constructor, creates timer instance. Optional startCountDown to start timer
* Methods:
timerInstance.start();
- begins timer, if the timer is already playing (not paused) start will restart it
timerInstance.stop();
- pauses timer
timerInstance.reset( [ startCountDown ] );
- resets timer time to 0
* Properties:
timerInstance.paused;
- boolean; determines whether timer is playing (true) or not (false)
timerInstance.time;
- number; time in milliseconds the timer has been running
