/**
 * Retrieves the minimum value of a collection. If the collection is empty or
 * falsey `Infinity` is returned. If a callback is provided it will be executed
 * for each value in the collection to generate the criterion by which the value
 * is ranked. The callback is bound to `thisArg` and invoked with three
 * arguments; (value, index, collection).
 *
 * If a property name is provided for `callback` the created "_.pluck" style
 * callback will return the property value of the given element.
 *
 * If an object is provided for `callback` the created "_.where" style callback
 * will return `true` for elements that have the properties of the given object,
 * else `false`.
 *
 * @static
 * @memberOf _
 * @category Collections
 * @param {Array|Object|string} collection The collection to iterate over.
 * @param {Function|Object|string} [callback=identity] The function called
 *  per iteration. If a property name or object is provided it will be used
 *  to create a "_.pluck" or "_.where" style callback, respectively.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {*} Returns the minimum value.
 * @example
 *
 * _.min([4, 2, 8, 6]);
 * // => 2
 *
 * var characters = [
 *   { 'name': 'barney', 'age': 36 },
 *   { 'name': 'fred',   'age': 40 }
 * ];
 *
 * _.min(characters, function(chr) { return chr.age; });
 * // => { 'name': 'barney', 'age': 36 };
 *
 * // using "_.pluck" callback shorthand
 * _.min(characters, 'age');
 * // => { 'name': 'barney', 'age': 36 };
