This task is about creating doxygen documentation for the classes
PopupItem and MapInfoItem
The documentation should contain a description that tells what the class is all about including possible use cases.
All methods should be described - ideally without reusing words from the method names. Special focus should be put on methods that are not self-descriptive.
