FilterLibraryMask (gephi 0.9.3 API)

```
public interface FilterLibraryMask
```
Classes that implements this interface can be registered to the filter library to programmatically enable or disable categories, i.e. filters container. That is useful for instance to disable filters working on undirected graphs if the current graph is directed.
When registered, masks are asked whether the category is valid.
