this patch removes the in-file lists in favor of a global list of in
the COPYING file. this is done because (a) maintaining a list of
authors at the beginning of each source file is a major pain in the
a**, (b) for this reason, 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 replacing the lists...)
most of these people like to inflict pain on themselfs (i.e., warnings
in their own code), but they usually don't like if pain is inflicted
on them by others (i.e., warnings produced by external code which they
use). This patch should make these kinds of people happy. I'm not
really sure if the code is easier to understand with this, but at
least clang does not complain for most of the warnings of
"-Weverything" anymore.
I have trouble seeing why this can possibly physically justified
(because oil is once the wetting and once the non-wetting phase), but
things seem to be like this as the documentation says that in case of
chosing the relperm hysteresis model 0 via the EHYSTR keyword,
hysteresis is only used for the non-wetting phase.
