"""Example: Custom snapshot defaults
Here we modify snapshot defaults globally, instead of per assert.
This gives the ability to modify the snapshot functionality to your hearts content
and then simply re-use them, without having to pass those defaults to every assert.
Especially useful if there's a lot of tests that need to modify the default behaviour.
