[ERROR] implicit val uFormatter = new VCFOutFormatter(SupportedHeaderLines.allHeaderLines)

In this specific use case I'd like to add Freebayes-specific headers to the ones we already support, something like

val freebayesHeaderLines = Seq( ... )
val headerLines = SupportedHeaderLines.addHeaderLines ++ freebayesHeaderLines
implicit val uFormatter = new VCFOutFormatter(headerLines)

+1, although perhaps we should do a name change as well? SupportedHeaderLines makes it sound like all other header lines will be lost.

Ah that's right, we combine those in the input VCF with our supported header lines, so I don't actually need to define freebayes specific header lines. How about rename to VCFHeaderLines?

That's a little too close to htsjdk.variant.vcf.VCFHeaderLine for me.

ok, propose away :)

Perhaps DefaultHeaderLines, since they're what we add by default.
