In this update, the generic type `BranchUtil<T>` has been refactored to
`BranchUtil`. Additionally, the method `thenSupply` on `BranchUtil`
instances has been modified to use the non-generic form `<T>thenSupply`
to simplify the method's interface.
BREAKING CHANGE: The method `handle(Supplier<T> trueSupplier[,
Supplier<T> falseSupplier])` has been refactored to `<T>
thenSupply(Supplier<T> trueSupplier[, Supplier<T> falseSupplier])`; the
type signature for the `thenSupply` method has changed; ensure to update
any instances where it is invoked.
