• [x] tests tests tests
• [x] no mutable default arguments
• [ ] break into functions
• [ ] smaller helper function for doing a step and then backwards interpolation
• [x] decorator wrapper for mypy and numba.njit, passing on __annotation__
• [x] ensuring that stuff stays array and/or list when it is array and/or list
• [x] pass in cartesian coordinates + lookup table instead of pos_arr
• [ ] more descriptive names
• [ ] fragment-based code
• [x] pure internal movement (?) (get_inertia and get_barycenter might be useful)

perhaps (could be done for another MR)

• [x] profiling
