@Singleton
public class Common
extends java.lang.Object
```
This class provides configuration properties that are common to all modules of JATOS. It mostly takes parameters from application.conf. It is initialized during JATOS start (triggered in GuiceConfig). Since most fields are initialized by the constructor during the JATOS' start (triggered in GuiceConfig), it's safe to access them via static getter methods.
