 * This function is intended to replicate behaviour of the Array.filter() function but for Objects.
 * If an array is passed in instead then it will perform standard filter(). It is recommended to
 * always use the standard filter() function when it is known that the object is actually an array.
 * @memberOf module:objectHelpers
 * @param {Object|Array} obj - The Object (or Array) to be filtered
 * @param {module:objectHelpers~filterCallback|Function} fn - The function to be processed for each filtered property
 * @param {Object|Array} [thisArg] - Optional. Value to use as this when executing callback.
 * @returns {Object|Array}
