    MiniGenotypeLoader is simply the MultiParamLoader configured to load one kind of data: "org:" objects.

    methods, or you can use it as a guide for creating your own specialized class.

    Returned MiniGenotype pointer always references the the same object (MiniGenotypeLoader::genotype_object)
    which means you may need to copy the data from it before calling loadNextGenotype() again.
    In the default configuration (simple MiniGenotypeLoader) NULL is always final and should be used
    to finish processing.

    If the loader is configured to load other objects or stop on other conditions, NULL will also mean
    every condition other than "GenotypeLoaded". In such cases you need MultiParamLoader::getStatus(),
    MultiParamLoader::finished() and other methods to determine the real cause of NULL.
