Fixing an issue with Error no XiaLabCppLib available.

[ElieElHachem]

Hi there,
I just want to inform you that I've fixed an issue with the R packages. In the file NetworkUtils.R, under the function Compute.SteinerForest, I updated the function as follows:

  if (.on.public.web) {
    output <- XiaLabCppLib::call_sr(from, to, cost, node_names, 
      node_prizes)
  }
  else {
    output <- call_sr(from, to, cost, node_names, node_prizes)

Regards
