  I hope that this code will eventually be autogenerated.


  In this code, the convention is:

    ejs_pull_*()   from MprVar -> C structure
    ejs_push_*()   from C structure -> MprVar

  note that for ejs calls, pull only ever needs to do
  NDR_IN, and push only ever needs to do NDR_OUT. This is
  because ejs code is (at least for the moment) only used for
  the client, not the server

  also note that we don't need the NDR_SCALARS/NDR_BUFFERS stuff, as
  we aren't dealing with wire marshalling where scalars and buffers
  are separated
