Details - I have here some code to write any tetrahedral mesh in ALUGrid format.  The user can specify a partitioning to produce a collection of ALUGrid files which can be used by ALUGrid as a pre-partitioned mesh.

Current limitations are the restriction to tetrahedra, the source mesh must be serial, and writing an ALUGrid and reading it back in will probably lead to a different numbering.

Advantages over ALUGrid's built-in write() method are that it works with any gridview, even non-ALUGrid, and that the user can specify a partitioning.

Attached are two patches: the first is the writer itself, the second is a program that partitions the unit cube and write it a a collection of ALUGrid files.  The program should be seen as a proof of concept and is not supposed to end up in dune-grid in its current form.

I'd like your comments, please, especially from Robert :)
