Detailed Description

Helper class to safely sell a city improvement.

This class adds an action to a menu (via add_to_menu) to sell a city improvement. When the item is activated, the potential gain is displayed and the user is prompted for confirmation. If the user confirms, the improvement is sold.

The seller can also be used directly with its operator().

This class handles all corner cases where the city may be disbanded or the improvement disappear for some reason.
