    I did some testing.
    And some of the Markdown documents I used as samples
    Sometimes there are grammars close to exceptions.
    
    When I checked in jupyter,
    If you try to apply a syntax close to the exception,
    The structure of the changed html document is most similar to Markdown4j.
    (actually, some element is little different)
    If the structure of the document is similar, it is easy to implement the 
same experience as Jupyter in `LooknFeel`, so I chose Markdown4j which showed 
the most similar results.
    
    one problem is that if you run the markdown paragraph with the default 
interpreter,
    some results may look different.
    
    What do you think?
