Title: Allows for rolling timeouts (interval timeouts)

This will allow for users to have a rolling timeouts for callbacks that
should be called regularly.

How

`cb.interval(1000)` sets a timeout and has it reset on each iteration
`cb.interval(false)` clears interval, does not effect any current timers
