     Internal functions used by other MPI functions.

     'bin.nchar' is used to find the number of char in a binary 
     character vector (length 1) produced by  'serialize'.

     'mpi.comm.is.null' is used to test if a comm is MPI_COMM_NULL
     (empty  members).

     'string' create a string (empty space character) buffer.

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

     bin.nchar(x)
     mpi.comm.is.null(comm)
     string(length)

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

    comm: a communicator number.

       x: an R object.

  length: length of a string.

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

     'bin.nchar' returns the length of a binary char vector.

     'string' returns an empty character string.
