Description

Currently the Driver and Evaluator start only in a separate JVM process - that is, the entry point is always a public static void main() function. We have to be able to configure run REEF in the existing JVM process, possibly in parallel with other code in in the same process. Refactoring REEFLauncher into main()-running and Clock-running part would be the first step towards that.
