This demonstrates a few simple concepts, useful when using & testing http handlers. It shows different ways of writing a simple webservice with a single handler which renders a list of tweets.
The tweets package shows how we might fetch and return tweet data, but it
returns fake data for demonstration purposes.
The directories prefixed 1_, 2_, etc show a progression of how we might
build up the code to create a working & testable http handler. The aim being to
gradually introduce the key concepts.
