/**
 * This simple program has one class: Bird (plus a main class)
 * The Bird definition has three attributes, two overriding constructors,
 * and a getter and setter for each attribute.
 * 
 * Notice that the setter for attractiveness does a validity check
 * before it sets the value. This is part of the value of getters 
 * and setters. They allows the object to control how its attributes are 
 * accessed and changed.
 * 
 * In reality, there would be additional methods, like fly(),
 * eat(), and buildNest().
