+TODO: Must find a way of dynamically importing models
+
+``` python
+>>> from reference_model import reference_model
+>>> from vipscore_common.vips_model import VIPSModel
+>>> print(VIPSModel.__subclasses__())
+[<class 'reference_model.reference_model.ReferenceModel'>]
+>>> print(VIPSModel.__subclasses__()[0])
+<class 'reference_model.reference_model.ReferenceModel'>
+>>> t = VIPSModel.__subclasses__()[0]()
+>>> t
+<reference_model.reference_model.ReferenceModel object at 0x7f8fab6dee30>
+>>> t.get_model_name()
+'Reference Model'
+>>> t.get_model_description()
+"\n        The model is a reference model for developers, showcasing best practices and functionalities of a model.\n        It's a simple day degree model for an imagined pest, and when thresholds are passed, the warning status progresses.\n        "
