Add support for mutating to/from the unsigned right-shift operator (>>>).

Thanks! Could you also add a trivial example of this operation to our integration tests?

The operation can go in:
https://github.com/stryker-mutator/stryker-net/blob/master/integrationtest/TargetProjects/NetCore/TargetProject/Constructs/CSharp11.cs

And I would expect that adding the operation changes the total mutants count for the integration test, this can be modified here: https://github.com/stryker-mutator/stryker-net/blob/master/integrationtest/Validation/ValidationProject/ValidateStrykerResults.cs

Thanks - I didn't find that as I assumed everything relevant was in the main Stryker .sln file.

Is there some documentation on how to setup these tests so I can get them passing locally?

If I try to run them as-is, I get errors about missing files:

InitCommandDefaults => Json file missing
CSharp_NetCore_SingleTestProject => System.IO.DirectoryNotFoundException : Could not find a part of the path 'C:\Coding\stryker-mutator\stryker-net\integrationtest\TargetProjects\NetCore\NetCoreTestProject.XUnit\StrykerOutput'.

I assume it involves replicating this?

It's OK, I've reverse engineered it.

I'll push up a commit with a script to make it easier for contributors in the future once I've updated the tests.

[martincostello]

Integration tests added.

[martincostello]

Looks like I need to update the results for the tests that run in AzDO too.

[martincostello]

Fixed.
