Bugfix: avoid using TimeMap without deck.

This made the simulator crash when there is no deck involved.
Use existing TimeMap, instead of creating new.

Bugfix: avoid using TimeMap without deck.
Suppress unused argument warning.
Cleaning up and preparation for eclipseState.
Bugfix:  Actually use column index ...
Base initialisation of SWL etc on EclipseState ...

Thus allowing an unmodified Norne deck.
Rename eclState to eclipseState.
Added some tests for the endpoint scaled relperm.

- satfuncStandard: Unscaled curves, using standard version of the
Gwseg model.
- satfuncEPSBase: Unscaled curves, but using the EPS version of
the Gwseg model.  There are some differences between this and the
standard version of Gwseg for derivatives at critical saturations.
The scheme for calculating the derivatives should be discussed.
(Will file a separate issue on this.)
- satfuncEPS_A: Scaled curves.  Scaling parameters specified via
SWL family.
- satfuncEPS_B: Scaled curves.  Scaling parameters identical to _A
but this time specified via the ENPTVD table.  Test currently
suspended due problems with eclipse-state.
- satfuncEPS_C: Scaled curves.  Scaling parameters identical to _A
but this time specified via Norne-like syntax (EQUALS, COPY etc.).
Forgot to list the DATA-files ...
Consistency between scaled and unscaled gwseg.

Modified the endpoint scaled version of SatFuncGwseg and updated
the tests accordingly.
Made hysteresis variant of gwseg consistent ...

... with the base gwseg behaviour.  Added test.

Initialization of SWL-family from EclipseState.  (Needs PR opm-parser/#278.)
Do not include shut wells in the well name to index map
The name to index map is used to make sure the correct wellstate values
are associated with the corresponding well. Shut wells should be
excluded from this mapping as no date is for shut wells are found in the
wellstates, instead 0 is outputed for the shut wells.

fix opm-parser find rule
Fixes missing return value in non-void function of WellsManager.

gcc warned about the following

/home/mblatt/src/dune/opm/opm-core/opm/core/wells/WellsManager.cpp: In function ‘std::array<long unsigned int, 3ul> WellsManagerDetail::directionIndices(Opm::CompletionDirection::DirectionEnum)’:
/home/mblatt/src/dune/opm/opm-core/opm/core/wells/WellsManager.cpp:191: warning: control reaches end of non-void function

To calm it I introduced a throw clause after the switch statements. Thus adding a new
enum value will raise a warning on smart compilers, hopefully.
