     Functions to start and stop a SNOW cluster and to set default
     cluster options. Wrapper around original start-stop commands from
     SNOW to hide  the cluster object.

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

     makeCluster( ...)
     stopCluster(cl)

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

     ...: cluster option specifications, for details see SNOW package.

      cl: cluster object.

_D_e_t_a_i_l_s:

     'makeCluster' starts a cluster of the specified or default type
     and returns NO reference to the cluster. The reference is stored
     in an internal  environment (.affyParaInternalEnv) and will be
     automatically used from the functions  in affyPara. For further
     parameters and documentation see the SNOW package. 

     'stopCluster' should be called to properly shut down the cluster
     before exiting R.  If it is not called it may be necessary to use
     external means to ensure that all slave processes are shut down.

_E_x_a_m_p_l_e_s:

       ## Not run: 
             makeCluster(2)
             stopCluster()
       
     ## End(Not run)
