/**
 * The Composite pattern is a partitioning design pattern. The Composite pattern describes that a
 * group of objects is to be treated in the same way as a single instance of an object. The intent
 * of a composite is to "compose" objects into tree structures to represent part-whole hierarchies.
 * Implementing the Composite pattern lets clients treat individual objects and compositions
 * uniformly.
 *
 * <p>In this example we have sentences composed of words composed of letters. All of the objects
 * can be treated through the same interface ({@link LetterComposite}).
