  default void executionStop(ISpockExecution spockExecution) {}
Is called after Spock finished executing tests.
<p>
Extensions get access to the {@link IStore} via the {@link ISpockExecution}
and can do some finishing action.
<p>
Note that values implementing {@link AutoCloseable} will be automatically closed
by the {@link IStore}, so there is no need to do this here.
