+  Class handling the writing of slow data. Strings to be written in the
   slow data file are checked that they do not contain control characters.
+  
+  1. Call constructor with desired identification and directory
+     for slow data file. The public ErrorCode variable will be zero 
+     if successful, otherwise contain the relevant errno.
+  2. Use NewEntry() to start a new entry with given variable name. A text
+     as second argument is optional.
+  3. If text should be added to an open entry, use AddToEntry(). It can
+     process printf()-style formatting.
+  4. The slow data file will be closed upon destruction of the instance.
