/*
*
* Este padrão tem a intenção de, dinamicamente, agregar responsabilidades adicionais a um objeto.
*
* Participantes:
* Component - define a interface para objetos que podem ter responsabilidades acrescentadas dinamicamente;
* ConcreteComponent - define um objeto para qual as responsabilidades adicionais podem ser atribuidas;
* Decorator - mantém uma referência para um objeto Component e define uma interface que segue a interface do Component;
* ConcreteDecorator - acrescenta responsabilidade ao componente
