the tested tuple is from Dune, std, or std::tr1.

For a tuple of references get() should still return a non-const reference,
even if the tuple itself is const:

  int n = 0;
  const tuple<int&> t(n);
  get<0>(t) = 1;  // post: n == 1

Without this property, tie() would be largely meaningless.

... with appropriate default parameters.  This leads to slightly
simpler code.  Note though that the method reportStream has
disappeared, and hence this patch may break some code.
I think that's acceptable, though, because the fix is trivial
and the reportStream method never appeared in a release.

Also, talk a little bit about the no-rvalues limitation.
