* Add Lattice Method and Quasi-random Method to monte carlo integration* Fix the "No-points in left/right half space" error in miser. Randomerrors like that are discouraged in a library. The routine shoulditerate over the dimensions choosing a point on each side of thebisection to ensure that the error does not occur.* VEGAS could estimate its roundoff error, caused by dividing up intomany boxes and then summing (I know this is ridiculous for anyrealistic case, but it shows up on the tests when integrating aconstant!).  In particular, there are some failures reported for theVEGAS constant tests on Windows.* VEGAS gives a negative chisq for some cases where there are wildlyinconsistent values.  Calculation should be improved so that chisq>=0.Also, when there are inconsistent values it might make sense to scalethe error by chisq, as is often done experimentally -- at least thatway the error would be increased.* The original VEGAS allowed to user to calculate other weightedquantities.  The appropriate way to implement it in GSL would be toprovide a separate routine which returns sample points and weights sothat the user can caculate any quantity.
