_D_e_s_c_r_i_p_t_i_o_n:

     Adds probe offsets to the groups in a CDF structure.

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

_U_s_a_g_e:

     cdfAddProbeOffsets(groups, ...)

_A_r_g_u_m_e_n_t_s:

  groups: A 'list' structure with groups. Each group must contain the
          fields 'tbase', and 'expos'. 

     ...: Not used.

_V_a_l_u_e:

     Returns a 'list' structure with half the number of groups as the
     'groups' argument (since allele A and allele B groups have been
     joined).
