Add JVM/Kotlin example

[nkiesel]

Very closely modeled after the Java version.

One pitfall is that the Fission JVM environment is stuck at Java 8. Therefore, the generated JAR file must be post-processed before it is deployed. Instructions are in README.md

Thanks a lot @nkiesel that was super fast :) I will take a look tomorrow and merge!

I did not change the specs file because I did not use them (I think). So, they are still saying "java" all over the place. I need directions on where to read up if/how to change them.

Tomorrow have come and gone.
