 * Is the given date tomorrow?

 * > ⚠️ Please note that this function is not present in the FP submodule as

 *
 * @param {Date|Number} date - the date to check
 * @returns {Boolean} the date is tomorrow
 * @throws {TypeError} 1 argument required
 *
 * @example
 * // If today is 6 October 2014, is 7 October 14:00:00 tomorrow?
 * var result = isTomorrow(new Date(2014, 9, 7, 14, 0))
 * //=> true
