> Spark provides the top() and takeOrdered() APIs that return "top" or "bottom" items from a given RDD. 
> It'd be good to have an API that returned the "top" values per key for a keyed RDD i.e. RDDpair. Such an API would be very useful for cases where the task is to only display an ordered subset of the input data.
