 * A simple non-optimized string tokenizer.
 * Example of use:
 * StringTokenizer("Now, this is a test!", " ,!") gives tokens "Now", "this", "is", "a" and "test" using nextToken().

       * Creates a StringTokenizer.
       * @param str The string to be tokenized.
       * @param delimiters String containing all the delimiter characters (i.e. the characters to be ignored).
       * @note Uses space, horizontal tab, carriage return, newline, form feed and vertical tab as delimiters by default.
