This package (and others) need to be reviewed/restructured.

• Some classes are general utility classes (BooleanUtil, ClassUtil, ExceptionUtil) and belong in a package such as info.magnolia.util
• Some classes are content utility classes (NodeDataUtil, ContentUtil and their inner classes, Visitor, ...) - these belong to a package such as info.magnolia.content(.util) (along with their related classes, which should be restructured too)
• Some others are specific to, say, installation tasks, security, etc, and should also be moved appropriately (i.e next to their usage)
