- CHANGED: Error struct has a new label field for labeling an error
- The label is what is printed to screen
- vtxbuf name lookup moved out of printErrorToScreen/print_error_to_screen
- NEW: acScalReductionTestCase and acVecReductionTestCase
- Define new test cases by adding them to a list in samples/mpitest/main.cc:main
- Minor style change in verification.c to make all Verification functions similar
and fit one screen
