```
public class MlHerbrandBase
extends java.lang.Object
```
Modified version of HerbrandBase that allows for modal formulas. The Herbrand base is the set of all possible ground atoms of some given first-order logic.
NOTE: We only allow to define a Herbrand base for signatures without function symbols.
