Integrate Smile ML library

This looks promising, but seems to need some non-Java libraries to be installed manually.

I believe DL4J ships the native BLAS libraries via Maven. Maybe the Smile ML guys could use these?

I wonder if the instructions on the repo are still up-to-date - there seems to be a ND4J module which uses the native mavenized libraries from DL4J/ND4J

I have been playing around with the CRF implementation; Either I am missing something or the implementation scales zero. Plain POS tagging example is extremely RAM greedy and slow.
