   * It is unfortunate that java.io.Writer is a class rather than an interface.
   * The serializer has a number of classes that extend java.io.Writer
   * and which send their ouput to a yet another wrapped Writer or OutputStream.
   *
   * The purpose of this interface is to force such classes to over-ride all of
   * the important methods defined on the java.io.Writer class, namely these:
   * <code>
   * write(int val)
   * write(char[] chars)
   * write(char[] chars, int start, int count)
   * write(String chars)
   * write(String chars, int start, int count)
   * flush()
   * close()
   * </code>
   * In this manner nothing will accidentally go directly to
   * the base class rather than to the wrapped Writer or OutputStream.
   *
   * The purpose of this class is to have a uniform way of chaining the output of one writer to
   * the next writer in the chain. In addition there are methods to obtain the Writer or
   * OutputStream that this object sends its output to.
   *
   * This interface is only for internal use withing the serializer.
