In particular, add two new helper functions
crit_sat_increasing_KR
crit_sat_decreasing_KR
which identify the critical saturations under the assumption of a
relative permeability curve that increases viz decreases as a
function of the specified phase saturation. Those helpers in turn
call a wrapper around std::lower_bound() and std::distance() to
affect the actual table scan.
Reimplement the 'critical_*()' helper functions in terms of
crit_sat_*_KR() to remove duplicated logic.
