Takes XY coordinates of two sets of locations and returns cross distance for all entries.

1	get_crossdist(xy1, xy2, id1 = NULL, id2 = NULL)

`xy1`	two column matrix of XY coordinates for first group
`xy2`	two column matrix of XY coordinates for second group
`id1`	optional names for first group
`id2`	optional names for second group

numeric scalar or vector
