    \brief The IDeviceFactory class implements an interface for classes that
    provide services related to a certain type of device.

    The factory objects have to be added to the global object pool via
    \c ExtensionSystem::PluginManager::addObject().

    \sa ExtensionSystem::PluginManager::addObject()

    \fn virtual QString displayNameForId(Core::Id type) const = 0

    Returns a short, one-line description of the device type.
*/

    \fn virtual QList<Core::Id> availableCreationIds() const = 0

    Lists the device types this factory can create.
*/

/*!
    \fn virtual IDevice::Ptr create(Core::Id id) const = 0
    Creates a new device with the id \a id. This may or may not open a wizard.
*/

/*!
    \fn virtual bool canRestore(const QVariantMap &map) const = 0

    Checks whether this factory can restore a device from the serialized state
    specified by \a map.
*/

    Loads a device from a serialized state. Only called if \c canRestore()
