modules coord2d

rust lib for coordinate in 2d system

example

```rust use coord2d::*;

fn main() { let coord1: coords::Coord = coords::new(3, 4); let coord2: coords::Coord = coords::new(5, 13); let sum: coords::Coord = coord1 + coord2;

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

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

println!("{:?}", line);
let h = vectors::new(a, b);
let m = h + l;
let s = h + l;
println!("\nlet h = points::new(a, b); | {:?}", h);
println!("\nlet m = h + l; | {:?}", m);
println!("\nlet s = h + l; | {:?}", s);

}

```

TO DO

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