CountMinSketch is not serializable

[gokyo]

Could we make com.clearspring.analytics.stream.frequency.CountMinSketch implementing java.io.Serializable please?

I am getting this error:
org.apache.commons.lang3.SerializationException: java.io.NotSerializableException: com.clearspring.analytics.stream.frequency.CountMinSketch
at org.apache.commons.lang3.SerializationUtils.serialize(SerializationUtils.java:156)

CountMinSketch has serialize and deserialize in the current implementation. It should be possible to extend the Serializable interface as well. Have you looked to see if using the serialize/deserialize methods is viable for you? Are you interested in submitting a pull request that makes the desired modification?

Using serialize and deserialize would make my code complex.
Best for me would be to implement Serializable as it requires only a simple change on your code, and no changes on my code.
I can create a pull request if it is fine for you guys.
Thanks

I created the pull request on here: #110
On my local machine the Maven build passed. Both mvn clean install test and mvn test -B build successfully. It is compatible with both Java 7 and Java 8.
But one of your three builds failed unfortunately: https://travis-ci.org/addthis/stream-lib/builds/136229647
I believe my code changes are fine.
Let me know if the change can be merged and released.
Thanks
