// This cs file is mainly responsible for the backend behind the implementation of the inventory
// (1) getInventory: Main function that is responsible for building the base inventory
// 1. Open up the inventory file in the debug folder
// 2. Parse through the data
// 3. Create and invItem that gets added to the total list of Inventory
// (2) getCategories: helper functon that is responsible for building the subcategory lists
// 1. Clears out the previous lists just in case
// 2. Scans through the listOfInv and makes a copy of each item and determines which categorical list to put it into
// (3) printCategories: Helper function that calls printList for all the categories
// (4) printList: Main function that prints the entire contents of a categoryList into the Console
// (5) updateInventory: Called after every checkout, this main function allows the inventory to be ready for the next checkout
// 1. Creates a new file of the inventory and sets it as the default for the next update to the inventory
// 2. Gets the current date and adds it to the file
