Functionality to compare reports in a diff view #3542
Description
For stryker-mutator/stryker-dashboard#266, I would like to have a way for the report to display only the changed mutations in a diff view.
We could also do some magic with the JSON from two reports in the dashboard, but somehow I feel like it's best to put this in the report instead.
Perhaps we can give it the diff in JSON ourselves, so that we only have to work on displaying it? I would like to know your thoughts on this :).
