major code rewrite.
-rays are now handled inside class Ray -constructRay function removed as the functionality is replaced by Ray's constructor - added an unnamed enum to make indexing Ray::m_points more clear - Ray::angle is used to keep track of the angle to +x, is updated when any point in Ray::m_points is updated - Helper.hpp has been renamed to Utility.hpp -all functions that were above main() are now in Utility.hpp -rays now behave like a light source -rays get sorted by angle and get placed into a TriangleFan which is drawn as the light source -added additional options to the imgui menu
