These four are for general start and stop procedures. The constructor and destructor concern themselves with the internal members common to all drivers, such as the current cursor and the access semaphore. Subclasses will probably end up using these to handle memory allocation-related issues, but likely not much else. Initialize() and Shutdown() are for general setup internal to the module. Note that if Initialize() returns false, the server will not use the module, call Shutdown(), and then delete it as accordingly.</P>
