+ * @name differenceInMinutes
+ * @category Minute Helpers
+ * @summary Get the number of minutes between the given dates.
+ *
+ * @description
+ * Get the signed number of full (rounded towards 0) minutes between the given dates.

+ * @param {Date|Number} dateLeft - the later date
+ * @param {Date|Number} dateRight - the earlier date
+ * @returns {Number} the number of minutes
+ * @throws {TypeError} 2 arguments required
+ *
+ * @example
+ * // How many minutes are between 2 July 2014 12:07:59 and 2 July 2014 12:20:00?
