real time analytics quite code excerpts are difficult to follow

we provide the code to follow in our references.

In https://github.com/citusdata/citus_docs/blob/master/use_cases/realtime_analytics.rst

Instead of providing the code to be copy/pasted we provided diff part. It is useful in terms of explaining the difference, however, makes following the document bit more difficult.

Can we also provide a link to updated code instead of just the diff ?
