list indices must be integers, not str

Tried gen_outline.py and failed.
Got the following error, as I'm not a developer I have no clue what have I missed..
Traceback (most recent call last):

It's a standard mongodb json extract.

For MongoDB you need to specify --each-line (JSON usually only has one object per file but Mongo breaks that rule and puts a bunch in the same file).

python gen_outline.py --each-line <yourfile>
python json2csv.py --each-line <yourfile> <outline file from previous step>

Hope that helps. I'll update the README with a call-out for Mongo so it's clearer to the next person.
