Started Spatial app

initial commit.
added shapefile for the pi locations
added files; load, api_urls, json_views, serializers

I have the REST framework working for the spatial web app
I was just thinking, maybe it's not a good idea to tell the world where the sensors are located...
Anyway, the app is up and running and can be easily modified.
