/**
* Modality sucks! ;) But it is easy to work with
* do exec() on a dialog and you know everything is funky.
* You only need to have one Dialog loaded and so on.
* This class helps you to work like with modality and help
* you to keep things in sync
* It's a template class but it sends signals once one Item is ready
* the signals contains the status and id of the item and then you
* can fetch it.
* Also if you edit an record external you can tell this class and it'll
* call the merge() function of your widget to maybe merge in these changes.
* It also supports multiple modes. Either it can create new dialogs
* for each item or it can queue them depending on your usage. But it is
* so smart that if only one item is shown that the queue bar is not shown
* See the example for simple usage.
