27// MTaskInteractive
28//
29// If you want to create a new task inside a macro you will have to compile
30// your macro using macro.C++, because the root interpreter cannot use
31// uncompiled classes. To workaround this problem you can write simple
32// funcions (which can be handled by CINT) and use MTaskInteractive.
33//
34// This is a simple way to develop new code in a macro without need
35// to compile it.
36//
37// Example:
38//    Int_t Process()
39//    {
40//       gLog << "Processing..." << endl;
41//       return kTRUE;
42//    }
43//
44//    void main()
45//    {
46//       MTaskInteractive task;
47//       task.SetProcess(Process);
48//       MTaskList list;
49//       list.AddToList(&task);
50//    }
