five-minute #geocoder for openaddresses (tecznotes)

Start with a clean server running a current version of #ubuntu LTS (long-term support); either 14.04 or 16.04 will work. Amazon has readymade Ubuntu images available on EC2, or a local copy running under Virtualbox will do for testing. Both the address import process and the Elasticsearch index are hungry for lots of memory, so pick a server with 4-8GB of memory to prevent failures.
