/**
 * Gets the maximum value of `collection`. If `collection` is empty or falsey
 * `-Infinity` is returned. If an iteratee function is provided it is invoked
 * for each value in `collection` to generate the criterion by which the value
 * is ranked. The `iteratee` is bound to `thisArg` and invoked with three
 * arguments: (value, index, collection).
 *
 * If a property name is provided for `iteratee` the created `_.property`
 * style callback returns the property value of the given element.
 *
 * If a value is also provided for `thisArg` the created `_.matchesProperty`
 * style callback returns `true` for elements that have a matching property
 * value, else `false`.
 *
 * If an object is provided for `iteratee` the created `_.matches` style
 * callback returns `true` for elements that have the properties of the given
 * object, else `false`.

 * @param {Array|Object|string} collection The collection to iterate over.
 * @param {Function|Object|string} [iteratee] The function invoked per iteration.
 * @param {*} [thisArg] The `this` binding of `iteratee`.
 * @returns {*} Returns the maximum value.
 * @example
 *
 * _.max([4, 2, 8, 6]);
 * // => 8
 *
 * _.max([]);
 * // => -Infinity
 *
 * var users = [
 *   { 'user': 'barney', 'age': 36 },
 *   { 'user': 'fred',   'age': 40 }
 * ];
 *
 * _.max(users, function(chr) {
 *   return chr.age;
 * });
 * // => { 'user': 'fred', 'age': 40 }
 *
 * // using the `_.property` callback shorthand
 * _.max(users, 'age');
 * // => { 'user': 'fred', 'age': 40 }
