Remove all data generated by Geo::Index from some or all points

The fields that will be removed are lat_rad, lon_rad, circumference, search_result_distance and antipode_distance.

Called on its own (with no point or points specified) this method will remove all generated data from all points in the index.

A list of additional keys to remove can optionally be supplied. To request vacuuming of all points with additional keys specified, use undef instead of \%point or \@points.

See also Sweep(…).
