[Validator] Removing the recommended Constraints subdirectory

[ThomasLandauer]

Since both the Constraint and the Validator are in the same directory, I can't see any reason for putting them into a subdirectory called Constraints. In other words: When keeping the Constraints subdirectory, what would be the recommended contents of the Validator directory?

• If you agree in principle, I'll change the other occurrences too.
• If you don't agree (i.e. want to keep the Constraints subdirectory), I suggest to rename it to Constraint, since all other directory names are singular too.

I do agree with these changes. At least that what I do in my applications too as the Validator namespace itself would otherwise be empty.

It looks OK to me too 👍

I'm done :-)
