* A intenção do padrão Proxy é fornecer um substituto ou espaço reservado para outro objeto para controlar o acesso a ele. Um proxy, em sua forma mais geral,
* é uma classe que funciona como uma interface para outra classe.
*
* participantes:
* Proxy - mantém uma referencia que permite ao proxy acessar o objeto real; fornece uma interface idêntica ao de subject, por esse motivo ele pode substituir o objeto
* real(Real Subject); controla o acesso ao objeto real, podendo ser responsvel pela criação e destruição;
* Subject - define uma interface comum para RealSubject e Proxy;
* RealSubject - define o objeto real que o proxu representa;
