/**
* This method is like `_.sortBy` except that it can sort by multiple iteratees
* or property names.
*
* If a property name is provided for an iteratee the created `_.property`
* style callback returns the property value of the given element.
*
* If an object is provided for an iteratee the created `_.matches` style
* callback returns `true` for elements that have the properties of the given
* object, else `false`.
*
* @static
* @memberOf _
* @category Collection
* @param {Array|Object|string} collection The collection to iterate over.
* @param {...(Function|Function[]|Object|Object[]|string|string[])} iteratees
* The iteratees to sort by, specified as individual values or arrays of values.
* @returns {Array} Returns the new sorted array.
* @example
*
* var users = [
* { 'user': 'fred', 'age': 48 },
* { 'user': 'barney', 'age': 36 },
* { 'user': 'fred', 'age': 42 },
* { 'user': 'barney', 'age': 34 }
* ];
*
* _.map(_.sortByAll(users, ['user', 'age']), _.values);
* // => [['barney', 34], ['barney', 36], ['fred', 42], ['fred', 48]]
*
* _.map(_.sortByAll(users, 'user', function(chr) {
* return Math.floor(chr.age / 10);
* }), _.values);
* // => [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 42]]
