Comment(by mmetz):

 `v.outlier` is not designed to separate first from last return of LiDAR
 point clouds. The purpose of `v.outlier` is to detect true outliers, i.e.
 erroneous data points. First and last returns are not erroneous data
 points but valid data points. First and last returns can be separated with
 the LiDAR filtering toolchain `v.lidar.*`, `r.in.xyz`, and in grass 7
 `v.in.lidar` and `r.in.lidar`.
