/**
 * 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.
 *
 * @short helps to live without modaility
