This PR allows parameter values to be saved in time responses as well as passing parameter values (via theparams keyword) for theinitial_response, ,step_response, andfinal_response functions (which call through toinput_output_response for nonlinear I/O systems).

With this functionality, you can do things like

    nlsys = ct.nlsys(        lambda t, x, u, params: params['a'] * x[0] + u[0],        states = 1, inputs = 1, outputs = 1, params={'a': 0})    timevec = np.linspace(0, 1)    resp = step_response(nlsys, timevec, params={'a': -0.5})

The simulation will run with params['a'] = -0.5 and this information will be stored inresp.params.
