Andreas Lauser 8e0e9e9d31 rename "(Volume|Flux)Variables" to "(In|Ex)tensiveQuantities"
"intensive" means that the value of these quantities at a given
spatial location does not depend on any value of the neighboring
intensive quantities. In contrast, "extensive" quantities depend in
the intensive quantities of the environment of the spatial location.

this change is necessary is because the previous nomenclature was very
specific to finite volume discretizations, but the models themselves
were already rather generic. (i.e., "volume variables" are the
intensive quantities of finite volume methods and "flux variables"
are the extensive ones.)

* \brief A water infiltration problem with a low-permeability lens
* embedded into a high-permeability domain.
*
* The domain is rectangular. The left and right boundaries are
* free-flow boundaries with fixed water pressure which corrosponds to
* a fixed saturation of \f$S_w = 0\f$ in the Richards model, the
* bottom boundary is closed. The top boundary is also closed except
* for an infiltration section, where water is infiltrating into an
* initially unsaturated porous medium. This problem is very similar
* the the \c LensProblem, with the main difference being that the domain
* is initally fully saturated by gas instead of water and water
* instead of a \c DNAPL infiltrates from the top.
