Owlapy Adapter

• infer_and_save method renamed to infer_axioms_and_save
• added infer_axioms method which behave similar to infer_axioms_and_save but will instead return the axioms as OWLAPY classes
• added more types of inference that can be used in the parameter inference_types for the above mentioned methods.
• renamed method generate_inferred_class_assertion_axioms to generate_and_save_inferred_class_assertion_axioms to avoid confusion.
• added docstrings for infer_and_save as well as for infer_axioms where its now clearer to know the valid input for the inference_types argument.

Google Console Indexing

• Added owlapys documentation to Google Search Console for better indexing.
  • file docs/googlec4c425077889c69c.html needed for verification by google. It should always be there so please do not remove.
