+   
+   Compare a file list with a local directory 
+   
+   The Compare class looks at the file list and then generates events
+   to cause the local directory tree to become syncronized with the 
+   remote tree.
+   
+   The Correct class takes the events and applies them to the local tree.
+   It only applies information that is stored in the file list, another
+   class will have to hook the events to actually fetch files for download.
