| 16 % Returns a timestepper for integrating the discretisation in time | |
| 17 % method is a string that states which timestepping method should be used. | |
| 18 % The implementation should switch on the string and deliver | |
| 19 % the appropriate timestepper. It should also provide a default value. | |
