/**
* This method is like `_.sortBy` except that it sorts by property names
* instead of an iteratee function.
*
* @static
* @memberOf _
* @category Collection
* @param {Array|Object|string} collection The collection to iterate over.
* @param {...(string|string[])} props The property names to sort by,
* specified as individual property names or arrays of property names.
* @returns {Array} Returns the new sorted array.
* @example
*
* var users = [
* { 'user': 'barney', 'age': 36 },
* { 'user': 'fred', 'age': 40 },
* { 'user': 'barney', 'age': 26 },
* { 'user': 'fred', 'age': 30 }
* ];
*
* _.map(_.sortByAll(users, ['user', 'age']), _.values);
* // => [['barney', 26], ['barney', 36], ['fred', 30], ['fred', 40]]
