Andreas Lauser 290584dddc clean up the licensing preable of source files
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.))

* \brief Problem where liquid water is first stopped by a
* low-permeability lens and then seeps though it.
*
* Liquid water is injected by using of a free-flow condition on the
* lower right of the domain. This water level then raises until
* hydrostatic pressure is reached. On the left of the domain, a
* rectangular obstacle with \f$10^3\f$ lower permeability than the
* rest of the domain first stops the for a while until it seeps
* through it.
*
* The domain is sized 60m times 40m and consists of two media, a
* moderately permeable soil (\f$ K_0=10e-12 m^2\f$) and an obstacle
* at \f$[10; 20]m \times [0; 35]m \f$ with a lower permeablility of
* \f$ K_1=K_0/1000\f$.
*
* Initially the whole domain is filled by nitrogen, the temperature
* is \f$20^\circ C\f$ for the whole domain. The gas pressure is
* initially 1 bar, at the inlet of the liquid water on the right side
* it is 2 bar.
*
* The boundary is no-flow except on the lower 10 meters of the left
* and the right boundary where a free flow condition is assumed.
