Messaging Systems

• Advanced CSharp Messenger - Simple and efficient C# messaging system implemented with delegates and generics. Allows for logging of messages, has extended error detection, and adds extra protection from unexpected exceptions.
• BooMessenger - An efficient and simple to use messaging platform. Allows hierarchial grouping of message types.
