- Reimplemented 2D orbital mechanics functions in physics-2d.ts and encaspulated inside a `Physics2D` namespace. - Deleted physics.ts and moved the required functions into physics-3d.ts Further cleaning and reimplemntation will be done on the physics-3d.ts content. - Forced consistency on error handling : every raised error throws an `Error` object. - Commented sections relative to 2D physics and sequence generation.
