#
# converts a shapefile to an elasticsearch geo_point type with this mapping:

# {
#    "zipcode" : {
#        "properties" : {
#            "geometry": {
#                "properties": {

#                    }
#                }
#            }
#        }
#    }
# }
# 
# writes to stdout, can redirect to a file:
