Locking object for thread-safe access from simultaneous API requests.

BaseController components like RQController and EditController (offering HTML forms POSTing to AddController) will typically need to acquire a Read lock (EnterReadLock),
while components like AddController will typically need to acquire a Write lock (EnterWriteLock).

Locking is also need by when keeping storage up-to-date by Subscription to PropertyStream through OutsideLocalReceiver.

In ARCEvent typical components requiring read locks are -ProcessController-, -ESController- and -UIController- while -ASController- requires first a read lock (for parsing) and then a write lock.
