Barcode scanner using the scanning capabilities introduced with iOS 7.
The project (as it currently is) goes straight into scanning mode to which it constantly looks for barcodes to be scanned. In the viewDidLoad(), it sets the property found in the .h file (allowedBarcodeTypes) to only look for those specific barcodes. This is editable and extremely useful. When an allowed barcode is found, it takes in the data, creates a Barcode object with it, and adds that object to the collection of found barcodes. An alert is then presented telling the user the kind of barcode found, number of barcodes found in the past, and giving the option to scan again or be finished.
