CWContainer

Discussion

This class is a simple placeholder used when doing message threading. A container is composed of a CWMessage instance which might be nil, a parent, child and next CWContainer instances. For a full description of the implemented algorithm, see message threading. Instance variables of this class must be accessed directly (ie., without an accessor) - for performance reasons.
