Created a QML View Component for the UnrimpExample Item
The SlideOut Component recenter itself on resize of the parent container
Don't recreate the example when it is already current.
Use a QVector as container instead of QList
converted ExampleItem to QObject base class -> it can be made available to QML
the ExampleModel type is now registered as a "normal" type to QML
the ExampleItem type is registered as an uncreateable type to QML (only existing instances will be referenced)
added a get(<index>) method to the model which can be invoked by QML to get the ExampleItem at the specified index.
Removed exampleModel member from UnrimpItem.
now an ExampleItem instance is passed to the UnrimpItem instance instead of an index.
Added an EmptyExample type which is used when no example is set to the UnrimItem. The EmptyExample does only a clear with black as color
