0. Create views for the daily/monthly sales stats

1. What are the best selling months?

2. For every month, we want to see the followings:
- Percentile rank
- Distance rank
- Bucket ID (with equal CAPACITY buckets, and *NOT* equal WIDTH buckets!)
- Next month's total
- Prev month's total
- First total of the year
- Last total of the year

3. Create a smoothed/"spike removed" statistics from the daily stats!
