[Dune-devel] PromotionTraits broken

[Oliver Sander]

Hi Christoph,
sorry about that.  Please pull dune-common and try again.  As it turns out, with our current compiler
requirements the PromotionTraits class is not necessary at all in dotproduct.hh, and I simply removed
it completely.
Best,
Oliver
