Detailed Description

This implements a pure C++ Latch providing lock-S (shared) and lock-X (exclusive).

The concept used here allows X requests to be prioritized faster and more smoothly than standard implementations. It uses a no-lock strategy whenever possible and reverts to lock and wait in race condition.
