Question about "size_" of RouteLogic

[K Sun <ksun@essex.ac.uk>]

Hello,
    I am sorry that I have not found where the "size_" (RouteLogic) has 
been configured and what the meaning of "size_" (RouteLogic) is.
    In the constructor of RouteLogic, size_ has been configured as 0. 
However, following "Simulator instproc run", I did not find where the 
size_ has been reconfigured but the truth is it is indeed reconfigured. 
    I have also checked the code about setting up a new node. I have 
not found something about it either. 
    I really hope some body can give me an instruction or any 
implication.
    
    Thanks in advance!
