/**
 * {@link OptionHandler} for the option terminator <tt>--</tt>.
 *
 * <p>
 * This {@link OptionHandler} can be used to implement the special token
 * <tt>--</tt> that indicates that the rest of tokens are not options, but arguments.
 *
 * <p>
 * For example, if you have the following class:
 *
 * <pre>
 * <code> 
 * class Foo {
 *  {@literal @}Argument
 *  {@literal @}Option(name="--",handler={@link StopOptionHandler}.class)
 *   List&lt;String> args;
 *
 *  {@literal @}Option(name="-n")
 *   int n;
 * }
 * </code></pre>
 *
 * <p>
 * The command line <code>-n 5 abc def</code> would parse into {@code n=5, args={"abc",def"}},
 * but <code> -- -n 5 abc def</code> would parse into {@code n=0, args={"-n","5","abc","def"}}.
