This class automatically extracts the contents of a Multifile to the current directory (or to a specified directory) in the background.
It is designed to limit its use of system resources and run unobtrusively in the background. After specifying the files you wish to extract via repeated calls to request_subfile(), begin the process by calling run() repeatedly. Each call to run() extracts another small portion of the Multifile. Call run() whenever you have spare cycles until run() returns EU_success.
