13 * Sort a list of objects by a list of props (if first prop value is equivalent, sort by second, etc).

18 * @category List
19 * @sig [k] -> [{k: v}] -> [{k: v}]
20 * @param {Array.<string>} props A list of properties in the list param to sort by
21 * @param {Array.<object>} list A list of objects to be sorted
22 * @return {Array.<object>} A new list sorted by the properties in the props param
23 * @example
