/*
* Okay, it's nice that this was documented and all, but I at least understood very little
* of it, so I'm going to attempt to explain the data structures in here a bit more.
*
* For efficiency, many data structures are kept.
*
* The first is a global list `watchentries':
* hash_map<irc::string, std::deque<User*> >
*
* That is, if nick 'w00t' is being watched by user pointer 'Brain' and 'Om', <w00t, (Brain, Om)>
* will be in the watchentries list.
*
* The second is that each user has a per-user data structure attached to their user record via Extensible:
* std::map<irc::string, std::string> watchlist;
* So, in the above example with w00t watched by Brain and Om, we'd have:
* Brain-
* `- w00t
* Om-
* `- w00t
*
* Hopefully this helps any brave soul that ventures into this file other than me. :-)
* -- w00t (mar 30, 2008)
