case class ConstantStep(value: Double, time: Time) extends Ordered[ConstantStep] with Product with Serializable

Exponential recency-weighted average. This is similar to a weighted average, but instead of weighting by the count, it uses a constant weighting factor.

TODO consider changing Numeric to ToDouble?

TODO there is some interesting thing going on here, where you're summing up constantly weighted factors... and then in the importance weighting you're doing the same thing, you just send in a different weight every time.

The time is a way of skipping big swathes and injecting zeros in, but it's really the same.

You can maybe also think about this like you're just keeping track of some weighted numerator, but, same thing, injecting more sum of the weights into the denominator, but nothing, zeros, into the top.

That would be a nice thing to unify together.
