/**
* A TimerEvent is a single event that is processed by a Phaser.Timer.
*
* It consists of a delay, which is a value in milliseconds after which the event will fire.
* When the event fires it calls a specific callback with the specified arguments.
* 
* TimerEvents are removed by their parent timer once finished firing or repeating.
* 
* Use {@link Phaser.Timer#add}, {@link Phaser.Timer#repeat}, or {@link Phaser.Timer#loop} methods to create a new event.
*
* @class Phaser.TimerEvent
* @constructor
* @param {Phaser.Timer} timer - The Timer object that this TimerEvent belongs to.
* @param {number} delay - The delay in ms at which this TimerEvent fires.
* @param {number} tick - The tick is the next game clock time that this event will fire at.
* @param {number} repeatCount - If this TimerEvent repeats it will do so this many times.
* @param {boolean} loop - True if this TimerEvent loops, otherwise false.
* @param {function} callback - The callback that will be called when the TimerEvent occurs.
* @param {object} callbackContext - The context in which the callback will be called.
* @param {any[]} arguments - Additional arguments to be passed to the callback.
