/**

 * Clase en memoria para registrar y gestionar los comandos que vamos

 * realizando. La forma en que ha sido implementada esta clase, en vez de una

 * ?nica lista para albergar los comandos de deshacer(undos) y los de

 * rehacer(redos), se ha optado por dos pilas una para deshacer(undos) y otra

 * para rehacer(redos), de esta forma : Cuando se a?ade un nuevo comando, se

 * inserta este a la pila de deshacer(undos) y se borra de la de

 * rehacer(redos). Si se realiza un deshacer se desapila este comando de la

 * pila deshacer(undos) y se apila en la de rehacer(redos). Y de la misma

 * forma cuando se realiza un rehacer se desapila este comando de la pila de

 * rehacer(redos) y pasa a la de deshacer(undos).
