+ChannelSync is a virtual base class (aka interface) used by the RSS downloader.
+When you instantiate a downloader, you are required to give it a pointer to this interface.
+ 
+The downloader will call:
+ 
+	BeginChannelSync();
+	for (;;) // however many it encounters
+	  NewChannel(newChannel); // called once for each channel it downloads
+	EndChannelSync();
+ 
+If you have a class or data structure that wants updates, you'll have to mix-in
+this interface or implement a data-structure-babysitter class (or however you want to deal with it)
+ 
+See the "WireManager" for an example of how to use it
