Add Matrix stitching

Allow both horizontal and verticle stitching for a photo matrix as is done in the Gigapan series of software starting at $79 this has the added benefit of allowing someone with an older camera to take a group of 4 to 6 megapixel images and combine them to create a 20 to 50 and more megapixel image without the need to spend thousands on new cameras and lenses. This would give the program an ability not found in many under $100 point and shoot cameras that can do panorama images in the camera.
