add a template specialization for the for loop of an empty tuple (!158) · Merge requests · dune-fem / dune-fem

Martin Alkämper requested to merge bugfix/forloop-for-empty-tuple into master Jul 19, 2017

this is for example used, if one constructs the checkpointer without data, and just wants to preserve the persistentcontainer

maybe one wants to add a static_assert to check that the container is really empty, but that can only work within the apply method and I am not sure how to do that.

@martin.nolte: could you have a quick look at it?
