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

     This internal function merges results from Message Passing
     Interface (MPI) client nodes.

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

     rpart.permutation.mergeResults(results)

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

 results: A result list as returned by the clusterCall function of
          'Rmpi'.

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

     A list with the following elements: 

       R: Integer vector such that the ith element is the number of
          replicates having a better relative error than the original
          model for the i-split subtree.

       X: As above, but using cross-validation error instead of
          relative error.

       N: Integer vector such that the ith element is the total number
          of replicates reporting error values for the i-split subtree.
