This enables `ebos` to run Norne and other non-trivial data
sets. While at it, adapt the tolerances by `ebos`.
This patch only affects the research simulator, i.e. `flow` is
unaffected by it.
this is a compile time switch with the intention to be able to more
easily turn experimental features that are not yet considered to be
production quality on and off. DUNE has a similar mechanism (i.e., the
`DUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS` macro), but it relies on
the preprocessor.
For now, the property does not have any effect.
This reverts commit c873e8c92da389bc1d6bc4ed2a5241faddfa7630.
since OPM/opm-simulators#1287 has been merged there are no "in tree"
upstreams which use that mechanism anymore.
this now works with the unmodified master version of flow from
opm-simulators. we take the liberty to emit a deprecation warning,
though. this complicates things quite a bit.
