Hi Ovidiu!

Thanks for this commit. 

A few questions:

- Did you update the README? THe original commit did not commit a new README file. Maybe you did it later.

The docs say:

   <section id="kex.r.stats.get_statistics">
+               <title>
+               <function moreinfo="none">stats.get_statistics</function>
+               </title>
+               <para>Print the list of available internal statistics.</para>
+               <para>Parameters: <emphasis>statsid</emphasis> - which statistics to
+                       be printed. If set to 'all' then all statistics are printed; if
+                       set to 'statsgroup:' then all statistics in the group are printed;
+                       if set to 'statsname' then the statistics identified by the name
+                       is printed.</para>


"all statistics" - does this really apply to ALL - user configured and produced by other modules? Or just the kex module stats?
Maybe a clarification would be good. If it's all, including other modules, there's an overlap with stats and counters.
