Joel Bernstein updated SOLR-11943:
----------------------------------
Description:
This ticket will add the following functions / features:
1) *latlonVectors* function: Reads a list of tuples that contain a *location*
field type and returns a *matrix* of lat/long vectors.
2) Add support for *haversinMeters* distance measure.
With the addition of these two functions we'll have the ability to do various
distance based machine learning algorithms (distance matrices, clustering, knn
regression etc...) with location data.
