the in-file lists of authors has been removed in favor of a global list of authors in the LICENSE file. this is done because (a) maintaining a list of authors at the beginning of a file is a major pain in the a**, (b) the list of authors was not accurate in about 85% of all cases where more than one person was involved and (c) this list is not legally binding in any way (the copyright is at the person who authored a given change, if these lists had any legal relevance, one could "aquire" the copyright of the module by forking it and removing the lists...) the only exception of this is the eWoms fork of dune-istl's solvers.hh file. This is beneficial because the authors of that file do not appear in the global list. Further, carrying the fork of that file is required because we would like to use a reasonable convergence criterion for the linear solver. (the solvers from dune-istl do neither support user-defined convergence criteria not do the developers want support for it. (my patch was rejected a few years ago.))
