  /**
   * Adds property declarations to generated Objective-C for annotated fields.

   * See <a

   * >Apple's &#64;property documentation</a>.
   * <p>
   * Notes:
   * <ul>
   *   <li>Invalid attributes are reported as errors.</li>
   *   <li><b>readwrite</b>, <b>strong</b>, and <b>atomic</b> attributes are removed
   *     since they are defaults.</li>
   *   <li>Strings will include the <b>copy</b> attribute.</li>
   * </ul>
   * <p>
   * Example:
   * <pre>
   * class Foo {
   *   &#64;Property("copy, nonatomic") protected String bar;
   * }</pre>
   * generates:
   * <p>
   * <pre>
   * &#64;property (copy, nonatomic) NSString *bar;</pre>
