Two level comment

Two Level (or Top Levels) Comment, as its name tells, is a small module that allows you to keep exactly two levels of comment. It could be used for Question/Answer style nodes.

For each node type, there are three comment mode:

• The core's flat mode
• The core's threaded mode
• The TLcomment's mode: like the threaded mode, but you can descend only maximum one level

TLcomment forces comment pid change (not the faked max-level mode with css using indent:0 that does not sort comments by date). However it keeps the "real" pid in a seperate table for other usage.

It departed from flatcomments: #627164: Limit threaded depth. However there is really nothing in common between two modules.
