Holds all relevent information for a channel. 

This class represents a channel, and contains its name, modes, time created, topic, topic set time, etc, and an instance of the BanList type.

.SS "void chanrec::DecUserCounter ()"
.PP
Decrement the channel 'user counter' The channel user counter is a reference counter which holds the number of users on the channel. If it decremented to 0 then the channel is removed from the system. Modules may alter the reference count to hold channels open which have no users and would normally be deleted once empty.Definition at line 208 of file channels.cpp.

Returns the parameter for a custom mode on a channel. For example if '+L #foo' is set, and you pass this method 'L', it will return '#foo'.
