Experimental idea: IsBetween with explicit Inclusive and Exlusive boundaries

[FreeApophis]

Main Idea:

I want a "IsBetween" extension on number types (just int in the experiment) which I can chose if the boundary are inclusive or exclusive.

12.IsBetween<Including, Excluding>(0, 20)

This was a lot easier than I thought, I defined a common interface IIntervalBoundary and two implementations Inclusive and Exclusive with private constructors and public implicit operators.

Sorry for the noise, I was too eager in deleting branches 🙈
