/**
* a function to be used mostly for animations
* which takes a number and performes a callback function every time that number is updated
*
* in modern browsers this function will match the client screen refresh rate
*
* **Syntax** `requestNum(options, callback)`
*
* @param {Object} options
*
* @param {(number|Array.<Number>)} [options.from]
*
* start form this number/s
*
* takes one number or array of numbers
*
* **Initial Value** `0 | [0, 0 , ...]`
*
* @param {(number|Array.<Number>)} options.to
*
* ends at this number/s
*
* takes one number or array of numbers
*
* @param {Number} [options.duration]
*
* the duration the function will take to change the number (in milliseconds)
*
* **Initial Value** `350`
*
* @param {Number} [options.delay]
*
* delay time before starting (in milliseconds)
*
* **Initial Value** `0`
*
* @param {Boolean} [options.yoyo]
*
* go back to the start point if true
*
* **Initial Value** `false`
*
* @param {Boolean} [options.yoyoDuration]
*
* the duration to go back to start point (in milliseconds)
*
* **Initial Value** `duration`
*
* @param {Boolean} [options.yoyoDelay]
*
* delay time before starting the yoyo (in milliseconds)
*
* **Initial Value** `delay`
*
* @param {Boolean} [options.replay]
*
* replay count after the first play
*
* infinite if replay === -1
*
* **Initial Value** `0`
*
* @param {linear" | easeInSine" | "easeOutSine" | "easeInOutSine" | "easeInQuad" | "easeOutQuad" | "easeInOutQuad" | "easeInCubic" | "easeOutCubic" | "easeInOutCubic" | "easeInQuart" | "easeOutQuart" | "easeInOutQuart" | "easeInQuint" | "easeOutQuint" | "easeInOutQuint" | "easeInExpo" | "easeOutExpo" | "easeInOutExpo" | "easeInCirc" | "easeOutCirc" | "easeInOutCirc" | "easeInBack" | "easeOutBack" | "easeInOutBack" | "easeInElastic" | "easeOutElastic" | "easeInOutElastic" | "easeInBounce" | "easeOutBounce" | "easeInOutBounce"} [options.easingFunction]
*
* Timing functions specify the rate of change of the number over time.
*
* Takes a String or Function
*
* **Initial Value** `linear`
*
* @param {Function} callback
*
* this function will be called every time the number/s is updated
*
* this function take parameter/s which represent the updating number/s
*
* **Syntax** `function name(x, ...) { //... do somthing with (x , ...) }`
