Comment

Before classifying an ontology with the reasoner provided by this plugin it is neccessary to save the currently loaded ontology. Right now, due to some limitations of the plugin, it cannot pass direclty an ontology from Protege to the reasoner, so the reasoner has to reload the ontolgy from its owl file.
