/**

Class used to handle asynchronous events within a DSS session. Currently this

is only used to handle GetEvent() calls. It sets up an active object when a 

client makes a GetEvent() call, and completes it when ready, or cancels it

if the client so wishes.

Only one outstanding active object per client session is permitted.
