Phase 2 Release

For this release we generated 52 weeks of sales data as well as all of the inventory management data. We included the python scripts that were used to generate this data. We also populated our Postgres data tables with the data that was generated. We have included the scripts that were run to read the data from the CSVs that were generated and populate our tables. We also have included 15 SQL queries that provide us with information that will be useful for the POS application.
