JDJ article availalbe

My first published article become available from JDJ web site some time ago. I cannot say that I'm completely satisfied by it.

• It does not completely match the original idea and some important related things have been just mentioned in the final version because of size constraints.
  
• The language and style are the result of difficult compromises between me and other author, so it could have been better and more consistent.
• Also almost all references has been cut out during internal review cycle "because other articles on the site do not do it". I personally prefer articles that mention its sources.
  

But it was the first article that I have written myself and overall working on it was a good experience.
