Problems with Reading in Data

I've rediscovered the problem with using Xta/Xda for reading in data on a mesh. Reading in a mesh is ok but data is not. Here is why:

      The problem is in xdr_io.C, subroutine read_mesh.  In particular, look
      at lines 2099-2131, which is supposed to add foreign_ids to nodes.  This
      actually never happens which causes the code to crash when you try to
      read in data to those nodes.

      This never happens because mesh_data is null because it is supposed to
      be passed in as an argument but in the call to read_mesh (line 1924 or
      1947) mesh_data is not passed in.  Fixing this is not as easy as it
      looks.

      There is more to it if you want to investigate.  Try it for a simple
      example (ex12) and see what happens for you.  Hopefully I've made a
      mistake and I'm wrong.
