@gdfm, @karande I think that the code has improved a lot and it's already
there. My main concern right now is how to read sparse instances in the sparse
instance format ( like "{1 0.24, 434 0.34, 500:1}") and not only in the dense
instance format (like "0.223, .2323, 1").
The code to convert strings to dense and sparse instances is in
org.apache.samoa.instances.ArffLoader, and it uses java.io.Reader to get the
raw data. One way to do this could be that KafkaReader extends Reader, and then
use ArffLoader to get the instances using the KafkaReader.
