[CASHeW-s-Editor] Factory implented

[Xianfeng Liu]

Hi,
 I haved  changed the parser to use factory to generate nodes. Ravish, I think 
you should get my email this time, because the mail list works again. As you 
told me you will come to tha lab to work with me, I waited you until 6pm, but 
you did not come. The small bug I told you yesterday which we have solved 
before haven't been changed back. I will appreciate that you can change it 
because its in your parser function i think. I am not sure I will go to the lab 
and I can not find you via MSN or IRC. if you recieve this letter, can you 
reply it ? Thanks!
