Class LoggerMDC
The LoggerMDC class provides mapped diagnostic contexts.
A Mapped Diagnostic Context, or MDC in short, is an instrument for
distinguishing interleaved log output from different sources. Log output
is typically interleaved when a server handles multiple clients
near-simultaneously.
This class is similar to the LoggerNDC class except that
it is based on a map instead of a stack.
