```
public abstract BinaryDerivation @Nullable [] instantiate(VarInfo vi1,
                                                          VarInfo vi2)
```
    Create a set of derivations from two base variables. If the base variables aren't worth deriving from, returns null.
    
    Parameters:
    
    vi1 - the first of the two base variables
    
    vi2 - the second of the two base variables
    
    Returns:
    
    a set of derivations based on two base variables. We allow more than one because two base variables may have multiple derived variables, per type of derivation. Can also be null if the two variables have nothing to derive from.
