public class LabelNormalizer
extends Object
```
Normalizes votes on labels according to project config.
Votes are recorded in the database for a user based on the state of the project at that time: what labels are defined for the project. The label definition can change between the time a vote is originally made and a later point, for example when a change is submitted. This class normalizes old votes against current project configuration.
