Upgrading Zookeper and Curator libraries to 3.5.4-beta and 4.0.1. Cleaning pom file.
SlimSync has changed location of some classes.
Removing duplicit classes which were previously moved to package "managers".
Improvement in Process Launch task -when the worker is terminated then also launched process is killed as well. Before it run although the worker was already dead which was waste of time and resources.
Refactoring Worker's Collector thread (collects results from the execution pool) code by utilizing ExecutorCompletionService. Collector thread does not anymore check every 1s for results, thus wasting time. Instead, it keeps blocked until a result is available.
Several improvements:
Added option for export to append pareto front to existing file or overwrite it.
