Accept output from one Katana run to parse as a diff against another run

[neilwillgettoit]

I would like to have the output of one katana run be able to be fed into another katana run and produce a diff from the first run.

The workflow would be: 1. Run katana against site, save output 2. Pass output as a difference flag to another katana instance and produce only the differences between the first run and the second run.

Why would I like this? It would make it much easier to parse A/B testing on sites from various source IPs. I could do one run from us-east and then a second run from us-west to see what/if is different between the two runs from the two locations. On the second run from us-west I’d like to see just the diff from us-east output.
