The VRanges classes in the VariantAnnotation package is one such
class. It extends GRanges and adds a few more columns, like 'ref',
'alt' (and more).

I think the method name you want to look for is
"GenomicRanges:::extraColumnSlotNames", although I'm not sure why this
function isn't exported if it's something other packages should be
using / defining methods for.
