an object of GRanges

### Examples

    gr2 <- GRanges(seqnames=c("chr1", "chr1"),
    ranges=IRanges(c(7,13), width=3),
    strand=c("-", "-"), score=3:4)
    gr3 <- GRanges(seqnames=c("chr1", "chr1"),
                   ranges=IRanges(c(1, 4), c(3, 9)),
                   strand=c("-", "-"), score=c(6L, 2L))
    GRoperator(gr2, gr3, col="score", operator="+")
    GRoperator(gr2, gr3, col="score", operator="-")
    GRoperator(gr2, gr3, col="score", operator="*")
    GRoperator(gr2, gr3, col="score", operator="/")
    GRoperator(gr2, gr3, col="score", operator=mean)
