node_info question

[5taku]

hello
I'm trying to implement deeptralog content.

I have a few questions.

1. May I know what each column of node_info means?
   For example [1460.0, 13, -1, 0, 0, 0, 1666]
   [template id , service , ? , ? , edge attr ( log , server request , server response , client request , client response ) , type id].

2. I am curious about the way node is configured.
   Is it correct that node and event are composed of node_feature in order of time? I wonder if there is any other logic.

3. It seems that node_info should be configured in logic, and edge info should be configured next, but I wonder if it is correct.
