//TestIntArraySort.java
//Illustrates sorting an array of values according to
//the "natural order" of those values. This example is
//here to remind you that when you start looking at the
//other files in this directory the first thing you need
//to note and remember is that Employee objects, unlike
//integer values, do not have any "natural order".
