Publish ScalaDoc in maven central

[aosama]

Currently only JavaDoc is published in MavenCentral, need to look into a solution to merge both scaladoc and java doc if possible

[mmlinford]

Can you elaborate on what the difficulties were in publishing the scaladoc?

[aosama]

since we had java and Scala code there was no method to combine a single code documentation. Since most of our code is now in scala in the develop branch this is not a major issue anymore
