Synopsis:
   $chanusers([<channel>|*] [n1 n2,n3,n4])

Technical:
   This function returns a list of users currently on the specified channel.
   It will only operate for channels that the client is currently on.
   It will alternatively return a 0 or 1 if the specified nick(s) is on the
   channel.

Practical:
   This function basically does the same thing as NAMES, except is much
   faster.  However, it only functions on the client's current channels.
   If no channel is specified, the current is used.  

Returns:
   list of nicknames on specified channel, or nothing if error

Examples:
   $chanusers()                  shows users on current channel
   $chanusers(#foobar)           shows users on foobar if client is there
   $chanusers(#foobar luna)      returns 1 or 0 if the nick is on the channel
   $chanusers(#foobar luna q)
   $chanusers(#foobar luna,q)
