Annotate GD region overlap in AnnotateVcf

[epiercehoffman]

We want to add GD region overlap to the INFO field. It seems to make sense to do this in AnnotateVcf, probably within SVAnnotate. We could add a separate reference resource input specifically for GD regions, or we could make the noncoding bed file input into a flexible bed file input for which the user can specify the names of the INFO fields.
