@fnrizzi All vector space utils now have a passing MPI test for every serial test

something here is not right. i am a bit confused by the tests.
say that you want to the orthogonalizer.
can you please rework the tests such that:

• you create a local and global array
• each rank executes orthogonalizer on the what you call the GLOBAL array, and then you distribute the result
• then you do the orthogonalizer opoeration on the distributed array
  the last two things should be equivalent
