Here is the montecarlo optimizer. This patch should actually be
clean :-) Read the documentation and let me know if something doesn't
make sense.
Unfortunately, on flute the boost version installed generates a
warning in one of its headers and so -Werror has to be disabled. This
is not committed
I also moved the various optimizer tests into one directory since
there are too many test directories. The directions are not removed
since I don' trust for complicated move/remove/add combinations.
