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

     This internal function is executed on MPI client nodes and
     executes the rpart calls needed to generate permutation
     replicates.

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

     rpart.permutation.clientFunc(dataset, responseidx, model, formula, nperms)

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

 dataset: The dataset on which the rpart models will be built. 

responseidx: The index in 'dataset' of the response variable. 

   model: The original rpart model. 

 formula: The formula used to create 'model'. 

  nperms: Number of permutations to execute. 

_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.

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