Whoever came up with that keyword deserves a spanking because its
semantics are adapting thickness of the grid layers using the rock
properties without modifying the grid (and thus the output is not
showing what is actually used). As I understood that whole affair,
this is also done incorrectly, because the flow is not distorted in
depth direction but this the permeability should be divided by the NTG
values as the fluids seep through the thinner layers more quickly...
Anyway, we have to implement it, so here we go.
These are all keywords which are used by the Norne deck within some
property modifiers plus all variants of these. (sans the variants for
radial grids which are completely pointless IMO.) The chances that
keywords which have not been added yet can also be used are very close
to 100%, though.
Note that the default values for these keywords are currently
incorrect as the Eclipse RM states that the values must be looked up
in their corresponding table if the keyword is left unspecified (see
e.g. the documentation SWU). This probably means that we need to
implement "ghosty" keywords which magically appear if they have not
been explicitly specified or maybe we should only provide them in
EclipseState to be able to do the context dependent table look-up
"vodoo"...
this uses a small amount of template magic, to automatically change
the API of the GridProperty class depending on wheter it is
instantiated for double or for int.
