This is intended to supersede the RESTART_AUXILIARY tag. There is
no practical difference between vectors that are needed for restart
and vectors that are not needed for restart. They all go into the
SOLUTION section of a restart file.
Vectors tagged as RESTART_OPM_EXTENDED will not be output unless the
user does requests OPM-extended restart files.
Will use one common container for both the solution data required for the
restart, e.g. PRESSURE and SWAT and also the auxillary data like KRG and
FIP which is intended as extra information in the restart file, or
alternatively the summary file.
