b34781706c Adjusted the lambda search code so that when two lambdas give the same 
leave-one-out-error we always pick the bigger lambda.  This should be
slightly better since, all other things equal, bigger lambda usually
gives better generalization.

438ec2544a Setup the LU decomposition code to use LAPACK when available. I also removed the older 
version from numerical recipes and made everything depend on the lu_decomposition object
instead.  Finally, I added in a triangular solver that uses BLAS when available and made
the lu_decomposition object us it.
