Chain Events in Cairngorm allow you to chain up a series of Caingorm Events. This is especially useful when you are using a series of webservices and you need the results from the preceding one to execute the next one
Another example will be you need to execute a command that requires a prerequisite, such as authentication. You can use the Chain Event to execute the next command after authentication. It makes your code structured and easier to manage altogether
