Research direction

Start by reviewing the existing rr record command and the proposed rr diff entry point. The issue does not name implementation files or tests, so map how recordings are stored and compared before deciding on an approach. Done would mean defining and implementing a comparison that reports differences between the two example recordings.

Written by the indexing model from the issue text.

Description

Is there a way to diff two recordings on the same binary? I'm imagining something like this

$ rr record ./mybinary --control
$ rr record ./mybinary --test
$ rr diff
< runControlThing
> runTestThing
