Tk::Role::Dialog is meant to be used as a Moose role to be composed for easy Tk dialogs creation.
It will create a new toplevel with a title, and possibly a header as well as some buttons.
One can create the middle part of the dialog by providing a _build_gui() method, that will receive a Tk::Frame where widgets are supposed to be placed.
The attributes can be either defined as defaults using the _build_attr() methods, or passed arguments to the constructor call. The only mandatory attribute is parent, but you'd better provide some other attributes if you want your dialog to be somehow usable! :-)
