Provide a weight to bias towards choosing this strategy for a mutation.
The value of the weight is arbitrary, but a good default is "the number of
distinct ways in which this strategy can mutate a unit". This can also be used to prefer strategies that shrink the overall size of the result when we start getting close to MaxSize.
