/*
 * Objects of type InfoWindow are autonomous and must therefore always be instantiated using operator new.
 * In addition to this, InfoWindow does not have any non-static public class members.
 *
 * Since a (technically 100% correct) statement like
 *   new InfoWindow("foo", "bar");
 * is unintuitive, confusing or even objective to some people, this class uses a variation of the "Named Constructor Idiom".
 *
 * InfoWindow::Display("foo", "bar");
 * does the exact same thing as the above statement but looks a lot nicer.
