view objects. The addition of view objects in the fastforward project is expected to be brough into the trunk sometimes in the future, which is why we need to make this change. Tested Manually on Jam and Ostrich. Tested with h5commitest - Koala with intel compilers failed, but nothing had to do with those changes. error on Koala: error while loading shared libraries: libirng.so
