`gro` | A granges object
`upstream` | Distance in BP added upstream
`downstream` | Distance in BP added downstream
`pad` | Distance in BP added

### Value

A GRanges object with adjusted start and end values

### Examples

    #Read in CTCF Jurkat peaks in
    ctcf_j <- system.file('extdata','Jurkat_CTCF_chr1.narrowPeak',package = 'diffloop')
    ctcf <- bedToGRanges(ctcf_j)
    ctcf.pad <- padGRanges(ctcf, pad = 1000)
