/**
 * This function is intended to replicate behaviour of the Array.reduce() function but for Objects.
 * If an array is passed in instead then it will perform standard reduce(). It is recommended to
 * always use the standard reduce() 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~reduceCallback|Function|reduceCallback} fn - The function to be processed for each filtered property
 * @param {Object|Array} [initialValue] - Optional. Value to use as the first argument to the first call of the
 * callback. If no initial value is supplied, the first element in the array will be used. Calling reduce on an empty
 * array without an initial value is an error.
 * @returns {*}
