modules coord2d

rust lib for coordinate in 2d system

example 1

```rust use coord2d::*;

fn main() { let coord1: coords::Coord = coords::new(3.0, 4.0); let coord2: coords::Coord = coords::new(5.0, 13.0); let sum: coords::Coord = coord1 + coord2;

println!("{:?}", sum);

} ```

example 2

```rust use coord2d::*;

fn main() { let coord1: coords::Coord = coords::new(3.0, 4.0); let coord2: coords::Coord = coords::new(5.0, 13.0);

let h: vectors::Vector = vectors::new(coord1, coord2);
let l: vectors::Vector = vectors::new(coord1, coord2);

let m: vectors::Vector = h + l;
let s: vectors::Vector = h - l;

println!("{:?}", h);
println!("{:?}", m);
println!("{:?}", s);

} ```

TO DO

• [x] basic math
• [X] add fn give magnitude of vector
• [ ] add properties
