_D_e_s_c_r_i_p_t_i_o_n:

     Orders the columns of fields according to the values in a certain
     row of another field in the same CDF group. Note that this method
     requires that the group fields are matrices.

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

_U_s_a_g_e:

     cdfOrderColumnsBy(groups, field, row=1, ...)

_A_r_g_u_m_e_n_t_s:

  groups: A 'list' of groups.

   field: The field whose values in row 'row' are used to order the
          other fields.

     row: The row of the above field to be used to find the order.

     ...: Optional arguments passed 'order'().

_V_a_l_u_e:

     Returns a 'list' structure of groups.
