Add Event Wiring for All IActiveViewEvents Snippet (ArcObjects .NET 10.6 SDK)

Add Event Wiring for All IActiveViewEvents Snippet

Add Event Wiring for All IActiveViewEvents. Default member variables are declared and all events are wired by calling a set up function. Events can be removed by calling another remove function. Code functions are stubbed out for adding custom actions for the events.
