class_docstr: In-house ODE integrator.
  
  Parameters
  ----------
  n_steps : int
      Number of steps to perform.
  step_type : str
      Type of integration step.
      Possible values are `euler`, `rk2`, `rk4`.
  save_result : bool
      If True, result is stored after calling `integrate` or `integrate_t`.
docstr: Integrate force.
  
  Parameters
  ----------
  force : callable
      Function to integrate.
  initial_state : array-like
      Initial state.
  end_time : float or None
      Integration end time.
  
  Returns
  -------
  result : OdeResult
