C++ Attributes: unhook

The unhook attribute is overloaded. Depending on which arguments are given, it does one of the following:

• Unhooks an event handler from an event
• Unhooks all event handlers from an event for a given receiver
• Unhooks all event handlers from an event source for a given receiver
