* Lattice MBR grid search. Enables a grid search through the four parameters (p,r,scale and prune) used in lattice MBR.
  See 'Lattice Minimum Bayes-Risk Decoding for Statistical Machine Translation by Tromble, Kumar, Och and Macherey,
    EMNLP 2008 for details of the parameters.
  The grid search is controlled by specifying comma separated lists for the lmbr parameters (-lmbr-p, -lmbr-r,
  -lmbr-pruning-factor and -mbr-scale). All other parameters are passed through to moses. If any of the lattice mbr
  parameters are missing, then they are set to their default values. Output is of the form:
   sentence-id ||| p r prune scale ||| translation-hypothesis
