/*
*
* A intenção do padrão Iterator é fornecer uma maneira de acessar os elementos de um objeto agregado sequencialmente sem expor sua representação.
*
* Participantes:
* Iterator - define uma interface para acessar e percorrer os elementos
* ConcreteIterator - implementa a interface do Iterator; mantém o controle da posição corrente no percurso do agregado;
* Aggregate - define uma interface para criação de um objeto Iterator;
* ConcreteAggregate - implementa a interface de criação do Iterator para retornar uma instância do ConcreteCreator apropriado;
