Hi All.

I updated the recently discussed RTL example to demonstrate the performance
gain that can be achieved by using the RTL transaction mechanism.

The original query, that involves a self-join of the ~20,000 row table on a
complex condition, currently takes ~79 sec. on my setup (1.5 Ghz, MinGW,
g++ -O2). Then a record is removed from the table, which invalidates all
the indexes built by that point. The transaction commit repairs indexes,
and the query is re-run.

Update, commit, and re-run together take just 1 sec.

Please take the example and the updated library (again, a few performance
issues were fixed) at the usual location:

Please note that the directory structure of the library has been
"boostified" so please ajust you include path accordingly (although I
haven't yet put "boost/rtl" into #include statements, so it should go into
the include path for now).
