update tracerARB-atlas: 1. I changed the 'mindAR' library to the 'AR.js' library and started writing the code again, 2. I brought the 'tracerARB-atlas' project to the level it was before I started writing the code again, 3. I corrected the rotation of the model relatively, and wherever you touch it on the screen, the model rotates, 4. I also added the 2nd marker, which, when it appears on the camera, another model appears on the screen.
