/**
 * This test answers the question of whether we can:
 *    1.)  Compile a script using an engine created on the main thread.
 *    2.)  Eval that script (also on the main thread) to produce an object with immutable methods *and* mutable methods which *modify* internal object state/properties encapsulated/protected within a closure.
 *    3.)  Safely invoke the objects immutable methods from *ANY* thread (often simultaneously).
 *    4.)  Safely invoke the objects mutable methods from *ANY* thread as long as the object is synchronized (e.g. not invoked *simultaneously* from multiple threads).
 *    5.)  Safely invoke immutable methods from multiple threads while a synchronized mutable method is being simultaneously executed in another thread.
 *  6.)  Variables declared within the scope of the objects methods (not object properties), are not affected by executing that same method in other threads simultaneously.
