[Boost-users] Interval Library?

I think I am looking for functionality that is contained with the Interval
library, but am having a hard time digesting the documentation for this
particular library.  

I would like an Interval that goes from a min_value to a max_value, where
each value is the previous value + N.

For example, the interval {2, 6, 10, 14, 18} has a minimum value of 2, a
maximum value of 18, and increments by 4.  Given this interval, I would like
a function, Foo, that works as follows:

Interval(2, 18, 4) 	i;

i.Foo(2) == 2
i.Foo(6) == 2
i.Foo(0) == 2
i.Foo(18) == 18
i.Foo(20) == 18
i.Foo(5) == 6
i.Foo(3) == 6

Is this something that can be done with the Interval library, or am I
missing the point? :) 

Thanks in advance for your help!
