**Functionality**
Paper bundles will be created by attacking a paper with a paper or photo. More papers and photos can be added to it over time by again attacking the paper bundle with it.
The paper bundle can be browsed smilar like a newspaper. The items viewed inside the bundle can be removed from it or edited.
Editing a paper or photo inside a bundle can be achieved by clicking the whole bundle with a stamp or pen.
Two verbs exist for renaming the bundle and unclipping all the items at once, namely "Rename bundle" and "Loose bundle".
