OurComparable Max

Geoffrey Challen // 2021.3.0

Create a public class named Max with a single class method named max. max should accept an array of objects that implement OurComparable and return the maximum. Assert that the array is not null or empty.

As a reminder, compareTo returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the passed object. OurComparable works exactly the same as the official Comparable interface, except it is slightly simplified and does not accept a type parameter.
