     Fetch a value of a netWorkSpace variable and write it to a file.

     ## S4 method for signature 'netWorkSpace':
     nwsFetchFile(.Object, xName, fObj)

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

 .Object: a netWorkSpace object.

   xName: character string giving the name of the variable to find.

    fObj: 'file' object or character string specifying file to write
          data to.

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

     The 'nwsFetchFile' method looks in the shared netWorkSpace
     '.Object' for a value bound to 'xName'; if it finds such a value,
     'nwsFetchFile' writes the value to the specified file and removes
     it from the variable. If no value is found, 'nwsFetchFile' blocks
     until a value for 'xName'  becomes available.
