 * NOTE THE @Override!
 * This method is actually overriding a method in the ListenerAdapter class! We place an @Override annotation
 * right before any method that is overriding another to guarantee to ourselves that it is actually overriding
 * a method from a super class properly. You should do this every time you override a method!
 * <p>
 * As stated above, this method is overriding a hook method in the
 * {@link net.dv8tion.jda.core.hooks.ListenerAdapter ListenerAdapter} class. It has convience methods for all JDA events!
 * Consider looking through the events it offers if you plan to use the ListenerAdapter.
 * <p>
 * In this example, when a message is received it is printed to the console.
 *
 * @param event An event containing information about a {@link net.dv8tion.jda.core.entities.Message Message} that was
 *              sent in a channel.
