PrimeNumbersTask example doesn't compile

[shnplr]

1. There is no default constructor in AbstractTask i.e. the example should call super(String).

   public PrimeNumbersTask(int numbersToFind) {
   super("")
   //initialize
   }

2. The return type of execute does not match the interface definition <V, C>
   i.e. shouldn't it return a List?

   @OverRide
   public List execute(Tracker tracker) throws Exception {
   while (!enough && !isCancelled()) {

[shnplr]

also perhaps

1. add process() method in the example to demonstrate UI control responding to publish(number)
2. show how the reference to 'taskManager' is created e.g. injected into a griffon controller
3. show how to create a taskId to register events on TaskManager
4. for javafx toolkit users any advice vs using native javafx task

The newly uploaded sample application gives more details on how this plugin can be used. It's not the final solution though as I believe it can be simplified even further, but it's a good start to get the feeling of the API. The guide will be updated soon.
