Description: Added a one-line optimization for initialization of the precissions list in def compute_bleu function.
Motivation: I have to do a total of 7 billion computations so I was looking at possibilities for optimizing the computation routine. I find that this change is about x4 faster for the operation, consisting of about 12% of total improvement for the function. Added a screenshots of my timings. See the diff between precissions_old and precissions_optim. Numbers are averaged over 10k computations.
