## Detailed Description

The **AtomicCounter** class offers thread-safe manipulation of an integer counter.

These are commonly used for building thread-safe 'reference' counters for C++ classes. The **AtomicCounter** depends on the platforms support for 'atomic' integer operations, and can alternately substitute a 'mutex' if no atomic support exists.
