/**
* This method is like `_.sortedIndex` except that it returns the highest
* index at which `value` should be inserted into `array` in order to
* maintain its sort order.
*
* @static
* @memberOf _
* @category Array
* @param {Array} array The sorted array to inspect.
* @param {*} value The value to evaluate.
* @param {Function|Object|string} [iteratee=_.identity] The function invoked
* per iteration. If a property name or object is provided it is used to
* create a "_.property" or "_.matches" style callback respectively.
* @param {*} [thisArg] The `this` binding of `iteratee`.
* @returns {number} Returns the index at which `value` should be inserted
* into `array`.
* @example
*
* _.sortedLastIndex([4, 4, 5, 5, 6, 6], 5);
* // => 4
