/**
 * This is an adaptor PrintStream that wraps a Writer.  Because Writer and PrintStream have different interfaces,
 * this is technically NOT a decorator. Instead, we can call it an adapter.
 *
 * Bytes are converted to chars using the platform default encoding.
 * If this encoding is not a single-byte encoding, some data may be lost.
 *
 * This class relies on WriterOutputStream, which is courtesy of
 * http://www.coderanch.com/t/278540/java-io/java/create-PrintStream-PrintWriter
 *
 * I needed this to replace System.out with a wrapped version of System.out
 * (Not sure if there is any reason you would want to do this...
 * feels rather like a hack!)
