/**

 * Wrapps a result object so it can be used as method parameter and changed within the method.

 * This is useful especially for simple data types like <code>Boolean</code> etc.<br>

 * Example (usage):<br><code>

 * 	public String myMethod(String oneParameter, ResultWrapper<Boolean> success){<br>

 * 	    __if (oneParameter.equals("foo")){<br>

 * 	    ____success = success.setValue(false);<br>

 * 	    ____return "Foo";<br>

 * 	__}else{<br>

 * 	____//don't change success<br>

 * 	____return "All the best";<br>

 * 	__}<br>

 * 	}

 * </code>

 * Here a String is returned but the boolean value may also be changed and it's value is useable

 * by the calling method
