MultipleOf<T extends num> class

Validates that a value is a multiple of the specified divisor.

Uses a floating-point-safe algorithm: divides input by divisor and checks whether the quotient is within _epsilon of a whole number. The naive input % divisor == 0 check fails for decimal divisors such as 0.1 due to IEEE-754 rounding (e.g. 0.3 % 0.1 is not exactly 0).
