[Nodeshot] two example of interactive elevation profile processing using gmap

[Nemesis]

I didn't know about this format. Hopefully a bit more studying in the
GIS world will make me able to make smarter decisions.

At the moment, as I wrote in the other email, I can just go as far as to
implement a javascript library like leaflet or openlayers and make the
tiles configurable by settings so admins of a Nodeshot instance can
decide which tiles to use.

In the future, hoping there will be more contributors and an awsome
documentation, we will probably able to develop cooler stuff!
