Thanks for this nice tool! The generated report is very useful, I noticed one issue only.

Let this be my hierarchy in the previous release:

interface SomeInterface {}

class SomeClass implements SomeInterface {}

And that's my hierarchy in the new release:

interface SomeInterface {}

interface AnotherInterface extends SomeInterface {}

class SomeClass implements AnotherInterface {}

Then the report will incorrectly state that SomeInterface has been removed from the set of interfaces implemented by SomeClass.
