VariantAnnotator can be called as a standalone walker or by another walker, as it is by the UnifiedGenotyper. UG now no longer computes any of this meta data - it relegates the task completely to the annotator (assuming the output format accepts it).
This is a fairly all-encompassing check in. It involves changes to all of the UG code, bug fixes to much of the VCF code as things popped up, and other changes throughout. All integration tests pass and I've tediously confirmed that the annotation values are correct, but this framework could use some more rigorous testing.
Stage 2 of the process will happen later this week.
