Add results table

Still need to add results

[martinjaggi]

instead of best speedup, let's only put the speedup at the max (or reasonable, fixed) number of workers, so 16?
then you can have 2 columns, one for total speedup (most important), and if you want a second one for compute only speedup. (and a column to say that #workers = 16)

and Bleu scores can have a decimal for clarity. 24.0 and 25.0 (minor nitpick :))

[martinjaggi]

if other experiments have a different max # workers that's ok too
