[Shashwat] Assignment submission

[shash-sharma]

Seems to work well, but there's a noticeable lag between dragging the points and seeing the change. Might just be my computer, but I've noticed consistently across all my assignments that my code is often significantly slower than what I think it should be, and I think it's because I'm not fully using Eigen's inbuilt functionality. I will continue to explore Eigen more.
