An activity delegate executes an activity that has a required signature, such as the ForEach<T> activity that requires an iteration variable or the Catch<TException> activity that requires an Exception.

There are multiple generic versions of this type that take from 1 to 16 arguments for the activity that is called. There are also ActivityFunc<TResult> types for delegates that return values.
