+   MultiCompressor
+   
+   Multiple output class. Takes a single FILE* and writes it simultaneously
+   to many compressed files. Then checks if the resulting output is 
+   different from any previous output and overwrites the old files. Care is
+   taken to ensure that the new files are not generally readable while they
+   are being written.
