fun validateButAtMost(atLeastTimes: Int, butAtMostTimes: Int, atLeastButAtMostCall: (Int, Int) -> String, atLeastCall: (Int) -> String, butAtMostCall: (Int) -> String, exactlyCall: (Int) -> String): Unit
Validates that atLeastTimes is not equal to or greater than butAtMostTimes; throws IllegalArgumentException otherwise, pointing the user to use the given exactlyCall in case atLeastTimes equals butAtMostTimes.
