static options() {
        return {};
    }
Returns the options object passed to the database for the table that represents
this Model class.

Returns an empty object by default, which means the database
will use default options. You can either override this function to return the options
you want to use, or assign the options object as a static property of the same name to the
Model class.

@return {Object} the options object passed to the database for the table
                 representing this Model class.
