This commit adds a new member function
Eclipse3DProperties::adjustSOGCRwithSWL
which mutates the SupportedKeywordInformation of the various *SOGCR*
keywords created by makeSupportedDoubleKeywords(). Specifically,
adjust*() installs new post-processors for the critical oil-in-gas
saturations--post-processors that subtract the (scaled) connate
water saturation from the defaulted SOGCR. This is only applicable
if the simulation run uses Family I (SWOF/SGOF) saturation function
keywords, because the SGOF table is implicitly defined in terms of
the connate water saturation.
