A structure entity version consists of all {@link SourceCodeChange}s applied in a version of an attribute, a class, or a method.
For each new version of an attribute, a class, or a method, a new structure entity version is created. @author Beat Fluri @author Giacomo Ghezzi @author zubi @author Michael Wuersch
