2.0.0

This is a major release of VariantValidator. It replaces UTA with our own solution VVTA. We have also significantly upgraded our gapped-alignment handling code, extending the test set. See the tests documents and commits for the issue numbers we have addressed during upgrade. We have also introduced exon/intron mappings for variants thanks to @kjwinfield and @kwi11iams

Special thanks goes to @ifokkema and @jtdendunnen for providing user-stories and bug reports throughout the build.

@John-F-Wagstaff deserves a ton of credit for developing VVTA and we are looking forward to generating the next release of this data for the new year
