  -----------
  Add stride option (default=1) to KDIndex 3D neighbor search (#2650)

* Add stride option (default=1) to KDIndex 3D neighbor search

* Simplify downsampling of the strided neighbor search, and add comments

* Use the new KDIndex stride option when computing covariance features (still default to 1)

* We do not use valarray in KDIndex
