 * Reldens - GroupsDataGenerator

 * This class will use a list of classes and a groups models list to generate the proper instances for each case.
 * This is outside and unrelated to the server storage space, because even if you don't use a storage you could still
 * create your models manually, populate them with the proper data and get your classes instances with this generator.
