docs: Saves the document to the database by either performing a POST (for a new document) or a PUT (complete document overwrite).
          If you want to only update the modified fields use the .patch() function.
          Use docArgs to put things such as 'waitForSync = True' (for a full list cf ArangoDB's doc).
          It will only trigger a saving of the document if it has been modified since the last save. If you want to force the saving you can use forceSave()
