correction: implementation is CN-specific
implement getChecksum() in the superclass
implement getChecksum (retrieves from system metadata)
use shared get() method from superclass
use shared getLogRecords method
Remove isAuthorized(), setAccessPolicy(), and getLogRecords() methods since they're implemented in the superclass.
use Permission, not Event for isAuthorized() methods
do not delete the access rules when we "archive" the document on "delete" (commented out for now)
allow reading from xml_revision table when we are the doc owner
CNCoreImpl is replaced by CNodeService
