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: Integrator step type.
