Description
    Runs multiple patch interaction models in turn. Takes dictionary
    where all the subdictionaries are the interaction models.

        // Exit upon first successful interaction or continue doing other
        // models. Returned interaction status will be true if there has been
        // any interaction (so logical or)
        oneInteractionOnly true;
