alternative country pcodes, building URIs automatically and norms

[vpcom]

On a location such as http://hxl.humanitarianresponse.info/data/locations/admin/ner/NG, we know from the triple store the country pcode is "NG", and following our URI patterns the country code is "ner".

I'm willing to make the distinction to be able to build the URIs with a script and following the URI pattern. I would say we can remove the "ner/" and we never use it. Why not? For the pattern the pcode is already unique).

About saying the pcode of Niger is "NG" when it should be theoretically "ner" looks inaccurate to me, but it is maybe acceptable not to address a strict normalization issue now.
