         Separated out data processing from the getter methods. Getter methods now only return hash data.
         Added methods and unit tests for update_data() and get_disk_attributes(). update_data() can be called at any point in a calling script to update the drive data. This makes it where Disk::SMART can be used in a script called by cron, or a continuously running daemon.
