Detailed Description

API for creating a series of AsyncCalls. This is necessary because the same AsyncCall callback must not be fired multiple times.

The call producer needs to accept and store a Subscription::Pointer. It also should provide some mechanism for adding/removing/changing the stored Subscription::Pointer.

The callback() method of Subscription::Pointer will spawn AsyncCall to be filled out and scheduled as needed.
