+//! A simple implementation of the IErrorRecorder interface for
+//! use by samples. This interface also can be used as a reference
+//! implementation.
+//! The sample Error recorder is based on a vector that pairs the error
+//! code and the error string into a single element. It also uses
+//! standard mutex's and atomics in order to make sure that the code
+//! works in a multi-threaded environment.
