[ns] bind and delay_bind_init_one

[Stagiaire IIE 2000 <thiam@etna.int-evry.fr>]

Hi all,
1) What is the difference between bind and delay_bind_init_one ?

2) I have a C++ variable declared in class A, B inherit from A. Do I have to 
bind it in B if I have to set it in B tcl class ?

Thanks,
Alioune.
