Switch to opts, tolerate max-iterations-exceeded.

1. Use opts.h for command-line parsing in wasserstein_dist.
2. Real relative error at the end of auction is stored in params,
   params is passed by reference.
3. If -e command line option is given to wasserstein_dist,
    relative error will be printed.
4. If -t option is given to wasserstein_dist,
   no exception will be thrown, if maximum number of iterations is
   exceeded.
5. Run wasserstein_dist -h to see all options.
