/**
 * {@code Game} class provides the actual HangMan game and and all associated
 * utilities for the same. It is highly dependent on the {@code HangMan} for
 * validaing each and every letter guessed by the current user. This class
 * implements both {@code ActionListener} and {@code KeyListener} for purpose of
 * taking input from both mouse click and keyboard (specifically for gueesing
 * the letter).
 * 
 * <p>
 * KeyListener might be a bit glitched since it demands Window Focus. I'm
 * working on solution to solve the same.
 * </p>
 * 
 * <p>
 * The class provides for a pluggable panel {@code p}.
