/*
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
