Andreas Lauser 69e6fb60a2 rename the tests/grids folder to tests/data
... since the "grids" in that folder are slowly accumulating
information. (e.g. the ART grid for the fracture mapper and ECLIPSE
decks in the future.)

* \brief Some simple test problem for the black-oil VCVF discretization
* inspired by an oil reservoir.
*
* The domain is two-dimensional and exhibits a size of 6000m times
* 60m. Initially, the reservoir is assumed by oil with a bubble point
* pressure of 20 MPa, which also the initial pressure in the
* domain. No-flow boundaries are used for all boundaries. The
* permeability of the lower 10 m is reduced compared to the upper 10
* m of the domain witch capillary pressure always being
* neglected. Three wells are approximated using constraints: Two
* water-injector wells, one at the lower-left boundary one at the
* lower-right boundary and one producer well in the upper part of the
* center of the domain. The pressure for the producer is assumed to
* be 2/3 of the reservoir pressure, the injector wells use a pressure
* which is 50% above the reservoir pressure.
