_D_e_s_c_r_i_p_t_i_o_n:

     Function to re-arrange CDF groups values in quartets.

     This 'function' is design to be used with 'applyCdfGroups'() on an
     Affymetrix Mapping (SNP) CDF 'list' structure.

     Note, this requires that the group values have already been
     arranged in PMs and MMs.

_U_s_a_g_e:

     cdfMergeToQuartets(groups, ...)

_A_r_g_u_m_e_n_t_s:

  groups: A 'list' structure with groups.

     ...: Not used.

_V_a_l_u_e:

     Returns a 'list' structure with the two groups 'forward' and
     'reverse', if the latter exists.
