          The sort_value member is a peculiar quantity. The connections are
          assembled in the WellConnections class. During the lifetime of the
          connections there are three different sort orders which are all
          relevant:
 
             input: This is the ordering implied be the order of the
                connections in the input deck.
 
             simulation: This is the ordering the connections have in
                WellConnections container during the simulation and RFT output.
 
             restart: This is the ordering the connections have when they are
                written out to a restart file.
 
          Exactly what consitutes input, simulation and restart ordering, and
          how the connections transition between the three during application
          lifetime is different from MSW and normal wells.
 
          normal wells: For normal wells the simulation order is given by the
          COMPORD keyword, and then when the connections are serialized to the
          restart file they are written in input order; i.e. we have:
 
               input == restart and simulation given COMPORD
 
          To recover the input order when creating the restart files the
          sort_value member corresponds to the insert index for normal wells.
 
          MSW wells: For MSW wells the wells simulator order[*] is given by
          COMPSEGS keyword, the COMPORD keyword is ignored. The connections are
          sorted in WellConnections::order() and then retain that order for all
          eternity i.e.
 
               input and simulation == restart
 
          Now the important point is that the COMPSEGS detail used to perform
          this sorting is not available when loading from a restart file, but
          then the connections are already sorted correctly. I.e. *after* a
          restart we will have:
 
               input(from restart) == simulation == restart
 
          The sort_value member is used to sort the connections into restart
          ordering. In the case of normal wells this corresponds to recovering
          the input order, whereas for MSW wells this is equivalent to the
          simulation order.
 
          [*]: For MSW wells the topology is given by the segments and entered
               explicitly, so the truth is probably that the storage order
               during simulation makes no difference?
