// he decides to use a very simple rule. In any selection of two or more wines, he
// will always buy the second-cheapest.

// Given an array of wine objects, write a function that returns the name of the 
// wine he will buy for the party. If given an empty array, return null. If given an
// array of only one, Atticus will buy that wine.
