/*
  The SummaryConfig.require3DField( ) implementation is slightly ugly:

  1. Which 3D fields are required is implicitly given by the
     implementation of the Summary() class here in opm-output.

  2. The implementation of the SummaryConfig.require3DField( ) is
     based on a hardcoded list in SummaryConfig.cpp - i.e. there is a
     inverse dependency between the opm-parser and opm-output modules.

  The test here just to ensure that *something* breaks if the
