It is based on 2D vector library I have prepared for future projects.
It contains blocks for 2-dimensional vectors operations: sum, dot and cross products, unit vector, perpendicular and parallel components, rotation etc. and basic drawing (arrow, angle). You can use arbitrary number of vectors, they are indexed by natural number.

You should not use directly vectors with indexes above 'number of Vectors' - there is a working space for this library.
