/**
 * 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 , ...) }`
