Luckily, this month I have managed to finish first basic features of my software toolbox. It can correctly discover geometric character of any given boundary, is able to recognize whether boundaries are near-twist, near-tilt or symmetric. It can detect, for now only for cubic system, if the boundary can be classified as CSL boundary. Now I am able to move to further, i.e. more interesting steps. Having a tool which can deal with one single boundary, one can process large date sets, and then see what happens!
