Removed database transfer and cleaned up unnecessary files (Participant,
Controller)
Many minor changes. Test code still not running because Version vector
is not properly initialized. Need to handle case where you hear from a
new node for the first time
Blank class for server_id
Added Creation and server_id handling
Implemented test cases. Code is working, except primary does not commit
tentative writes. Write log not managed properly. Retirement not
implemented.
