How to dynamically sort data by arbitrary column(s)
<p>Is there a data structure of combination of structures ( STL, Boost etc. ) that would allow me to sort data in memory like it is done in this table here <a href="http://en.wikipedia.org/wiki/List_of_cities_proper_by_population" rel="nofollow">http://en.wikipedia.org/wiki/List_of_cities_proper_by_population</a>

I would like a generic solution that can handle arbitray number and names of columns. Essentially similar
to what you get using sql's <code>order by clause</code></p>
