Fix SHUT wells
Shut wells are not added to the well list and thus not considered in the
simulator.

The shut well test in test_wellsmanager is modified to assert this
behaviour.

BUG: This change provokes an assert in the EclipeWriter as number of
wells in wellstate is different from number of wells in the schedule.
SHUT wells returns 0
Shut wells returns 0 for bhp and rates in the EclipseWriter
Make the comment in test_wellsmanager more precise
The comment now precisly says that Shut wells are not added instead to
the well list instead of removed.

Fix SHUT wells
fix problem with solver reastart, variable was not reset.
Also, the time step does only grow moderately after a solver restart.
remove unused typedef to avoid compiler warning and keep code clean.

Fix solver restart counter.
Merge pull request #672 from dr-robertk/PR/remove-unused-typedef-warning

remove unused typedef to avoid compiler warning and keep code clean.
BUGFIX. Do not increase well index for shut wells.
Shut wells are not added to the well list and the well index should
therefore not be increased when well control is set. This is similar to
whats is done for shut wells in createWellsFromSpecs.
The wellmanager test is modified to account for not adding shut wells
Shut wells are not added to the well list and the well manager test is
modified accordinly.

BUGFIX Shut wells
Bugfix: avoid using TimeMap without deck.

This made the simulator crash when there is no deck involved.
Use existing TimeMap, instead of creating new.
Merge pull request #676 from atgeirr/bugfix-simple-simulator

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.).
