* Rename the class Module to SafetyModule.
* Make the class SafetyModule abstract (as per intention of the meta-model).
* Align the naming of the ModuleRef class (Library elements) --> SafetyModuleRef.
* Add a migrator for ModuleRef elements. A migrator for Module elements is not needed since this class has been used like an abstract one.
* Change the getFileProject utility class to handle cases in which the passed element is the FileProject.
