cms-201Y-collision-datasets-hi: add hlt trigger path for hlt snippets

[katilp]

(closes #178 )

@tiborsimko if needed I can easily modify the script to produce exactly the same format as in previous years, let me know.

Compared to the previous text, adds the word "validated" in front of "run"

[tiborsimko]

The format is OK, although for better separation and readability we may want to add empty line before "High-Level Trigger path information.".

BTW I have split 2013 directory into cms-2013-collision-datasets-hi-ppref and cms-2013-collision-datasets-hi separate directories in my local WIP branch, as we had discussed about it live.

How would it affect the HLT trigger listing? Could we easily split them, or we'll have them in one place and use symlinks?

[katilp]

I'd rather have these lists in one place (with symlinks) as they come from the same source which does not distinguish the collision type.

Fine for adding the line. Can you easily do it when you're on it? I can do it as well.

[tiborsimko]

OK, I'll merge "as is" and then add separating lines whilst creating HTL trigger path records.
