_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:

_A_r_g_u_m_e_n_t_s:

_V_a_l_u_e:

     'reverse', if the latter exists.
