Description copied from class: BinaryDerivationFactory

Create a set of derivations from two base variables. If the base variables aren't worth deriving from, returns null.

Specified by:

instantiate in class BinaryDerivationFactory

vi2 - 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.
