Specific improvements

    +
  1. Fixed: GridGenerator::merge_triangulations produced sometimes invalid + orientations of faces. This is now fixed. +
    + (Daniel Arndt, 2014/06/30) +
    2. +
  2. Fixed: TrilinosWrappers::PreconditionAMG did not read user-provided constant modes (aka null space) when the null space dimension is one but not just the trivial one vector.
