> Currently distance measures are instantiated by passing the name of the distance measure to a function, for example the *knn* function can be passed the named parameter: distance="manhattan".
> This ticket will create a specific function for each distance measure which will be used to specify which distance measure to apply. With this design the *knn* function would be passed the function: manhattan() or any of the other distance measure functions.
> Sample syntax:
> {code:java}
> knn(a, b, manhattan())
> or
> dbscan(a, haversineMeters()){code}
