Allow for point-in-time snapshots for reports/dataset

[ssugar1]

datasets/reports only show latest data. Would like to be able to schedule each month to save a point-in-time snapshot of the report/dataset as it is at that time. Then I can show a client their report from this month, or last month, or one year ago. Not just the data as it is at the latest refresh
