15 % Returns a timestepper for integrating the discretisation in time
|
|
|
16 % method is a string that states which timestepping method should be used.
|
|
|
17 % The implementation should switch on the string and deliver
|
|
|
18 % the appropriate timestepper. It should also provide a default value.
|
|

19 % time_align is a time that the timesteps should align with so that for some

20 % integer number of timesteps we end up exactly on time_align
