/**
   * The <code>StreamTokenizer</code> class takes an input stream and
   * parses it into "tokens", allowing the tokens to be
   * Read one at a time. The parsing process is controlled by a table
   * and a number of flags that can be set to various states. The
   * stream tokenizer can recognize identifiers, numbers, quoted
   * strings, and various comment styles.
   * <p>
   * Each byte Read from the input stream is regarded as a character
   * in the range <code>'&#92;u0000'</code> through <code>'&#92;u00FF'</code>.
