Have removed the SimulatorState base class, and instead replaced with
the SimulationDatacontainer class from opm-common. The SimulatorState
objects were typcially created with a default constructor, and then
explicitly initialized with a SimulatorState::init() method. For the
SimulationDataContainer RAII is employed; the init( ) has been removed -
and there is no default constructor.
this basically means using Opm::EclipseState instead of the raw deck
for these keywords.
with this, property modifiers like ADD, MULT, COPY and friends are
supported for at least the PERM* keywords. If additional keywords are
required these can be added relatively easily as well.
no ctest regressions have been observed with this patch on my machine.
