/**
 * Implements the driver for the Template Method design pattern example.<p>
 *
 * Intent: <i>Define the skeleton of an algorithm in an operation, deferring 
 * some steps to subclasses. Template Method lets subclasses redefine certain
 * steps of an algorithm without changing the algorithm's structure</i><p>
 *
 * Participating objects are <code>SimpleGenerator</code> and 
 * <code>FancyGenerator</code> as <i>ConcreteClass</i>es. The 
 * <i>AbstractClass</i> is <code>DecoratedStringGenerator</code>.
 *  <p>
 *
 * In this example, the template method <code>generate(String)</code>
 * modifies a string in three steps and returns the result. While the 
 * SimpleGenerator does not change the string much, the
 * FancyGenerator turns the string to lowercase, then capitalizes all 
 * consonants and adds an explanantion to it.
 *
 * <p><i>This is the Java version.</i><p>
 *
 * Note that <i>AbstractClass</i> does in fact have to be an abstract
 * class (as opposed to an interface), to make it possible to define 
 * a default implementation for the template method.
