* This class is a little more complicated than what this example demonstrate
* This watcher is capable of handling nested progress. Since the Progress
* grows from [0 to 1] on a per file basis and we only have one instance of a
* watcher per association, we need some calculation to compute the global
* (total) progress
* In fact we simply divide the per-file progress by the number of files.
*
* This QtWatcher class will then update the progress bar according to the
* progress.
