Description

Follow on to
https://issues.apache.org/jira/browse/MADLIB-927

knn( point_source,
     point_column_name,
     label_column_name,
     test_source,
     test_column_name,
     id_column_name,
     output_table,
     operation,
     k
   )

Possible improvements:

1) The parameters 'point_column_name' and 'test_column_name' should support regular PostgreSQL expressions.

2) Should we infer 'c' or 'r' from the data types, rather than have to say explicitly?
