Scala shell for Voldemort (Not final)

Hi I have been working on a scala shell that integrates with the project.The patches making up the shell are attached along.

The details regarding the shell are mentioned at:
https://groups.google.com/forum/#!topic/project-voldemort/cYvrck65k9c

The code is not final yet, but I am yet confused over any additional features that should be added/would be good to add to the shell. Patches regarding nodeId should be ignored (i.e. ignore 5f41a93, fb09d88 and 747f95b)

The shell can be invoked with sh bin/run-class.sh voldemort.VoldemortScalaShell
