Port changes made to VGNCParser in ensembl-xref, including unit tests, back to ensembl:feature/xref_sprint.
Salvage more work from the xref sprint.
Increased test-suite run time.
Have you added/modified unit tests to test the changes?
If so, do the tests pass/fail?
Have you run the entire test suite and no regression was detected?
