/**
 * Basic example of QueryPath usage.
 *
 * This two-line example exhibits basic use of QueryPath. It creates a new 
 * HTML document and adds the typical 'Hello World' text to the body. It then writes
 * that information to standard out (which is flushed to a web browser in most cases.)
 *
 * The important methods covered here are {@link qp()}, which is the {@link QueryPath}
 * factory function, {@link QueryPath::find()}, which is the primary searching 
 * function, and {@link QueryPath::writeHTML()}, which is a utility function.
 *
 * This file is fully explained in the official QueryPath tutorial, located 
 * at {@link https://fedorahosted.org/querypath/wiki/QueryPathTutorial}
