This patch introduces a new macro DUNE_UNUSED_PARAMETER(parm) for marking
unused parameters that are there for a purpose (e.g. the prescribed interfac
The macro simply performs a cast to void. In addition all unused parameter w
that I found were removed.

With the exception of mpicollectivecommunication.hh
and propertymap.hh, which I didn't understand.

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.

Maybe  we can remove it soon if everybody moves to the new naming

I tried to keep the interface backward compatible. Still there might
be some issues if you used template meta programms specialised for Nil
or using the internal first and second. Please report them.

Note: There are still some issues:
Empty tuples are currently not supported!
