Emphasis on the minimal

This is a very bare bones approach to the task of mapping and was meant for dipping my toes into rtrees, cairo, caching, and other performance guides. I highly recommended osmnx for a more fleshed out project. The sydney_sample.png was rendered with tile resolution=1024 and query_limit=10000 for a more detailed result.
