Kill this Node including the 'logical contents' of the node. i.e.
the contents of the node that are self.members as well as non-members.
Example: A DnaSegment's logical contents are AxisChunks and StrandChunks
Out of these, only AxisChunks are the direct members of the DnaSegment
but the 'StrandChunks are logical contents of it (non-members) .

members and logical contents. These callers should use this method.
