Absolute distance between two sets of genomic regions

1	genomic_corr_absdist(gr1, gr2, method = mean, ...)

`gr1`	genomic region 1, a `GRanges` object
`gr2`	genomic region 2, a `GRanges` object
`method`	function in which input is a vector of distance and output is a scalar
`...`	pass to `method`

For regions in gr1 and gr2, they are all degenerated as single points which are the middle points of corresponding regions. For each middle point in gr1, it looks for the nearest point in gr2. Assuming the distance vector is d, the final statistic is method(d).

A single correlation value.
