/*
* note que quando vou buscar um objeto eles já estão instanciados.
*
* A intenção desse padrão é usar compartilhamento para suportar um grande número de objetos semelhantes de forma eficiente. O padrão visa minimizar o uso
* de memória no armazenamento de vários objetos através do compartilhamento das informações em comum que essas instâncias possuem.
*
* Participantes:
* Flyweight - é a interface que define como devem ser as classes que trabalham neste padrão. é importante citar que ela descreve como os dados extrínsecos são objtidos,
* ou seja, as operações que fazem essa transposição de informações;
* ConcreteFlyweight - são as classes que implementam o contrato IFlyweight e que devem permitir o comportamento. Essas classes mantém dados intrínsecos;
* UnsharedConcreteFlyweight - possuem as mesmas características do ConcreteFlyweight, no entanto não são objetos compartilhados. Isso porque este padrão permite
* o compartilhamento, mas não obriga que isso seja sempre seguido;
* FlyweightFactory - Classe que é responsável pela criação dos objetos, além de manter o repositório de objetos que implementam o Flyweight;
* Client - É quem utiliza os objetos IFlyweight, sempre os obtendo através do FlyweightFactory
