Save state in slot scheduler algorithm

[chrisbenincasa]

Would it be possible to save the state of the time / random slot scheduler to allow for picking the algorithm back up from the same place at a later time? Currently, these algorithms can quickly become very computationally expensive (a separate issue we should look into). If we could save the state of the algorithm, we'd be able to generate a static (fast) amount of days and then calculate the rest in the background. This requires some investigation.
