/**
* This class provides a 'no-op' Writer subclass.
*
* It is intended to perform the equivalent of writing to /dev/null on
* Unix systems, for software components that are designed to write to
* a Writer but which may also perform desired side-effects at the
* same time.
*
* By using NullWriter, such a component can be run once against the
* NullWriter to capture the side effects, then again at a later point
* against a functioning Writer to perform the actual I/O.
