This class generates composite numbers.
Public interface
This class generates a list of composite numbers made up of powers of 2, 3, and 5, which are less than some max value and returns the smallest composite number greater than some number given.
CompositeNumber cn(1000); Int n = cn.nextLarger(319); Int m = cn.nextSmaller(462); Int l = cn.nearest(462);
