Generic type for Count-Min Sketch

[arnaudfnr]

Hi guys,

First of all thank you the great work you put in this library !

I am using Count-Min sketch implementation and I wonder why the only supported types are "long" and "String".
Indeed, there are some types of object such as Doubles or Integers that are easily and for sure convertible to String.
For Objects in general, the method toString() could be called, like in the Murmurhash used in HyperLogLog.
Is there a specific reason that you decided not to use it for CountMinSketch ?

Best regards,

Arnaud
