/**
* This is a local Voldemort server that can be started and stopped. It is not mandatory to have Voldemort installed on
* your local machine. All dependencies that Voldemort server needs are given in the pom file. The config files can be
* stored in the classpath to keep the versions. Normally local server is only used in local machines for testing
* purposes.
* <p/>
* All configuration of server is done on config files.
* <p/>
* The server normally creates 1 node having several partitions. No need to have more.
