Computes the centroid of a multipolygon. Note that the centroid may not be contained in the multipolygon.

Parameters
pointsA list of lists of points composing the multipolygon.
holesA list of lists of lists of points indicating holes in the multipolygon. The ith list of lists of points is a list of polygons indicating holes in the ith polygon in points.
Returns
a GeoPoint indicating the centroid of the multipolygon described by points and holes.
