        Functionality:

        * WordMesh: new interface to record reference word string in alignment.
        * nbest-lattice: confusion networks can now record reference words
          if specified with -reference, and are preserved by -write/-read.
        * replace-words-with-classes now has option to process ngram count
          files (have_counts=1).
        * merge-nbest: new utility to merge N-best hyps from multiple lists.
        * wlat-stats: new utility to compute statistics of word posterior
          lattices.

        Bug fixes:

        * GT discounting: fixed anomaly due to different floating point
          precision on x86 platforms.
        * anti-ngram(1): documented options previously omitted.
        * WordMesh: reading/writing of confusion networks now preserves
          total posterior mass.
        * Changed the hypothesis alignment order in nbest-optimize to be
          more compatible with decoding in nbest-lattice: first align nbest
          hyps in order of decreasing (initial) scores, then align reference.
          nbest-optimize -no-reorder keeps the old behavior (with references
          anchoring the alignment).  All scores and initial lambdas are now
          used to compute initial posterior hyp probabilities to guide the
          hypothesis alignment; thus, it now makes sense to restart an
          optimization with partially optimized weights to revise the
          alignments.
        * nbest-optimize now warns about missing or incomplete score files.
        * Fixed a memory access error in nbest-optimize -1best.
        * Fixed weight normalization in nbest-optimize when first element is 0.
        * Miscellaneous fixes for compile under RH Linux 7.0.
