/**
* Confines any changes made to the meta classes of the specified classes to the
* annotated scope. This is done by installing new meta classes when the scope is
* entered, and restoring the previously installed meta classes when the scope is
* left. Note that this only works reliably as long as spec execution is
* single-threaded.
*
* If a spec class is annotated, the meta classes are restored to as they
* were before setupSpec() was executed, after cleanupSpec
* was executed.
*
*
If a feature method is annotated, the meta classes are restored to as they
* were after setup() was executed, before cleanup() is executed.
* For a data-driven feature method, meta classes are restored after each iteration.
*
*
*
Note: If this extension is applied, then it will use acquire a lock for
* {@link org.spockframework.runtime.model.parallel.Resources#META_CLASS_REGISTRY}
