fix: fixed update score, by implementing manhattan distance

See merge request !20

Fixed some issues i had with the tests, generally cmakelist did not work on windows, but this has been fixed and accounted for.

fixed update score by implementing manhatten distance to ensure we are looking at neighbors and not anything more than that

refactor: split up visualization, cleaned up code, and allowed the user to run hp model directly into hook

See merge request !19

- We had one big file earlier, this is now split into relevant .cpp and .h files
- Stuff like input, spheres, shaders, GUI etc has been split
- A user can now initialize an empty visualization, but a hook has also been added, allowing it to be called with a HPMODEL, such that we cna viualize folds directly from other files
- Did some nice cmakelist.txt stuff, to make it easier to run on mac and windows without much change

Feature/algorithm c

Fix: Fixed visualization, lines are now added sequentially

See merge request !16

Fixed visualization to add lines sequentially, rather than adding lines between all neighborign spheres.
