Description: Interfacing to Nocedal et al. L-BFGS-B.3.0 (See
        <http://users.iems.northwestern.edu/~nocedal/lbfgsb.html>)
        limited memory BFGS minimizer with bounds on parameters. This
        is a fork of 'lbfgsb3'. This registers a 'R' compatible 'C'
        interface to L-BFGS-B.3.0 that uses the same function types and
        optimization as the optim() function (see writing 'R'
        extensions and source for details).  This package also adds
        more stopping criteria as well as allowing the adjustment of
        more tolerances.
