[Bioc-sig-seq] GenomicRanges wishlist: IntervalTrees for GRanges

[Kasper Daniel Hansen]

I would like to see 'IntervalTrees for GRanges'.  Specifically, if I
am repeatedly doing findOverlaps lookups on a big GRanges, I want to
be able to store the IntervalTrees that (right now?) gets computed
each time.

This may of course already exist, in which case I would be satisfied
with a pointer :)

Thanks,
Kasper
