 * people.

 * required in the for loops. (This code demonstrates the new style for-loop
 *
 * Finally notice that when you create a new class like Staff, nothing needs to be changed
 * in the tester
 *
 * This program obtains a list of people and then categorizes them by their
 * actual class names.
