	/**
	* Isso é uma factory function, basicamente é como se tivesse instanciando uma classe, mas faço isso com function,
	* prefiro esse padrão do que usar classes. Eu tenho que chamar essa função globalmente antes de começar o app.
	*
	* IMPORTANTE: Não demorei nem 10 minutos fazendo essa porcaria, então sei lá, recomendo algo mais parrudão pra usar em prod.
	* Principalmente algo com tipagem melhor que vc consiga listar os eventos disponiveis e os parâmetros que cada callback recebe.
