More data -- this time testing the originally-provided one-level grouping:

   Muenchian code:   9796

   Sergiu recursive: 16016

However, the original code produces also the count of each group. This
is not a requirement for grouping and is not part of the Muenchian
method at all.

With counting removed, the results are:

   Muenchian code:     953
  
   Sergiu recursive: 15922

Thanks to M.David Peterson, who offered to host the test data on
www.XSLTBLOG.com

I'm sending the data to him in a moment.

The data I'm using is artificial but not at all unusual. It contains
183 different authors. In real cases data extracted from a database
will contain thousands of different objects (persons, authors,
employees etc.)


Cheers,
Dimitre.
