026/**
027 * An {@link Html} variant that produces <b>readable</b> (indented, multi-line) output with attributes
028 * quoted using single quotes.
029 *
030 * <p>
031 *    This is the first-class facade form of the single-quote readable HTML variant.  It pairs
032 *    {@link HtmlSerializer#DEFAULT_SQ_READABLE} with {@link HtmlParser#DEFAULT} and exposes the full
033 *    static shortcut surface bound to its own {@link #DEFAULT} instance.
034 *
035 * <h5 class='figure'>Examples:</h5>
036 * <p class='bjava'>
037 * <jc>// Using static shortcuts.</jc>
038 *    String <jv>html</jv> = HtmlSqR.<jsm>of</jsm>(<jv>myPojo</jv>);
039 *    MyPojo <jv>myPojo</jv> = HtmlSqR.<jsm>to</jsm>(<jv>html</jv>, MyPojo.<jk>class</jk>);
040 * </p>
041 *
042 * <h5 class='section'>Notes:</h5><ul>
043 *    <li class='note'>Because Java <i>hides</i> (does not override) static members, this class redeclares the
044 *       entire static shortcut surface of {@link Html} so that every shortcut is bound to this class's
045 *       single-quote readable {@link #DEFAULT} rather than the {@link Html#DEFAULT}.
046 * </ul>
