Make initial HR demo data more robust

For initial demo purposes a more robust initial data load would be extremely helpful in selling the model. Whether it is prepopulated or the SA can walk through loading it, there needs to be more date across significantly more period. This is so that the reports we demo look more like what the potential client would use once they populate the HR BPA with their data and we can properly demo the full functionality of the reports and Dashboards in the model.
