    Description

      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:

      knn(a, b, manhattan())
      
      or
      
      dbscan(a, haversineMeters())
