text: #include <Handle.hpp>
  A connection Handle of a (connected) slot which disconnects and cleans up (free all resources) the connection object in its destructor.
  After CleanupHandle was destroyed, the connection is no longer usable and all associated callbacks have been removed. If another Handle object shares the same connection, it will no longer be able to connect().
