1. Especially tried to fix the callback mechanism I previously used.
2. 'long sessionID' changed to 'int requestId'
3. Introduced a generic class VotingBoothResult
4. Quite some other local changes
Summary:
Planned some basic interfaces for my revised Voting Booth componenets.
No implementation yet, though...
Test Plan: There are none, yet
