* This class is provided as a container for Inkscape's various

*
* DialogManager is essentially a cache of dialogs. It lets us
* initialize dialogs lazily - instead of constructing them during
* application startup, they're constructed the first time they're
* actually invoked by Inkscape::Application. The constructed
* dialog is held here after that, so future invokations of the
* dialog don't need to get re-constructed each time. The memory for
* the dialogs are then reclaimed when the DialogManager is destroyed.
*
* In addition, DialogManager also serves as a signal manager for
* dialogs. It provides a set of signals that can be sent to all
* dialogs for doing things such as hiding/unhiding them, etc.
* DialogManager ensures that every dialog it handles will listen
* to these signals.
