docs: ***********************************************************************
  getInstance. Initializes a HashtableOnDisk instance over the specified
  FileManager, from the specified instanceid. The instanceid was
  used to originally create the instance in the createInstance method.
  
  @param filemgr The FileManager for the HTOD.
  @param auto_rehash If "true", the HTOD will automatically double in
  capacity when its occupancy exceeds its threshold. If "false"
  the HTOD will increase only if the startRehash() method is
  invoked.
  @param instanceid The instance of the HTOD in the FileManager.
  
  @return A HashtableOnDisk pointer
