Augmented Reality barcode & QR code navigation for >= Android 4.0

Uses the real time camera image to analyze it for barcodes and uses them for a navigation to a goal barcode. Arrows into the right direction are shown depending on a hardcoded 2D barcode matrix. The Features include the automatically taking of a photo when a barcode is detected. Audio guidance is possible too.
The barcode matrix is a 2D array of the values of the wished barcodes/qr-codes. The order within the matrix represents their "physical" position - e.g. one could mark physical boxes with the barcodes in the very same 2D order. I.e. if you look at the barcode located at index [0,0] it represents a box at the left top. If the goal barcode is at [2,2] - the searched box will be in the horizontal and vertical center (assuming a 5x5 matrix is used)
The navigation will lead you first to the correct horizontal position, by telling you at each barcode you look at, where you're located relative to the goal. As soon as you're at the correct horizontal position the navigation will continue to the right vertical position until the goal barcode / qr code is found.

Make sure the app has the required permission on start, as there is no runtime-check yet! (Camera, external storage)

The barcode/qr-code detection is based on Desmond Shaw's Android Barcode Reader https://github.com/DynamsoftRD/Android-Barcode-Reader
