'This method is called when "Save" is pressed on the Studio editor.
Note that after this method is called, the modulestore update_item method will
be called on this xmodule. Therefore, any modifications to the xmodule that are
performed in editor_saved will automatically be persisted (calling update_item
from implementors of this method is not necessary).
Args:
user: the user who requested the save (as obtained from the request)
old_metadata (dict): the values of the fields with Scope.settings before the save was performed
old_content (dict): the values of the fields with Scope.content before the save was performed.
This will include \'data\'.'

def editor_saved(self, user, old_metadata, old_content):

    pass
