Forecast water use into the future

[christophertull]

If scenario planning is enabled ( see issue #5 ), then instead of just looking retroactively, we should be able to forecast water use into the future.

The exact details are completely open, but some possibilities include:

1. Extrapolating past use into the future, either by copying directly or by averaging over previous years.
2. Creating a statistical model of water demand in aggregate for each customer class (care should be taken here so that factors like population growth can be factored in).
3. Creating a statistical model at the customer level and then aggregating up to each customer class. This would be the most complicated but also the most flexible.

Option 1 would probably be a good and relatively easy start, with option 3 probably being the best choice overall.

Hey @anudeepvanjavakam1 , can we call this one closed for now? Will leave #6 open since you are still tweaking it.

@christophertull Yes, this is resolved. We can close this.
