Fix targeted shrinking in USERNF #233

Closed xspirus closed 4 years ago

xspirus commented 4 years ago

This commit fixes #221 and updates the way the targeted implementation shrinks its instances. PropEr now tries to find the best shrinker between the original generator and the neighborhood function.

Users can now also specify ?SHRINK macros in the neighborhood function, which will take precedence.
