Sets the type of {@link VariableResolver} to use by specifying a simple class name associated with the
inner classes in that interface or a fully qualified class name. The assumption is that implementations
will allow a constructor that takes a {@code Map} which contains the bindings from the script engine context.
Implementations are can then decide how to resolve variables in the script based on that {@code Map} or some
other mechanism.
