SLTev evaluation is taking excessively long

[bhaddow]

Hi

Running SLTev sometimes takes excessively long to evaluate (about 10 minutes). An example is available at http://www.statmt.org/bhaddow/SLTev-slow-mwe/

I run with:

SLTeval  -i ende.teacher.k0.en-de.en.txt.slt en-de.de.txt en-de.en.txt.OStt -f slt ref ostt

Profiling the code, I see that it spends most of its time here:

SLTev/SLTev/delay_modules.py

Line 154 in 2d56dd0

def extract_match_tokens_based_on_time(estimat_times, display_times, start, end):

I do not know the code well enough to know what the problem is, but (eg) the two loops could be combined, and the iteration should use for x in list rather than range()
