 +hmm = lightweight direct alignment method (in our ACL/TSD article)
 +gizainter = GIZA++, intersection -- applied to hypotheses+references directly
 +gizadiag = GIZA++, grow-diag -- applied to hypotheses+references directly
 +czenginter = align source+CzEng to reference+CzEng, and source+CzEng to hypotheses+CzEng with GIZA++, intersection, extract hypothesis-reference alignments from there ("Dan's method")
 +czengdiag = same, but with GIZA++ grow-diag
