rustjsonderive

Derive the ToJson and FromJson for rust_json.

#[derive(ToJson)]

```rust use rustjson::ToJson; use rustjson_derive::ToJson;

[derive(ToJson)]

struct Simple { n: f64, #[rename = "sim.b"] b: bool, }

[derive(ToJson)]

struct Nest { a: Vec, s: Simple, }

[derive(ToJson)]

enum Enum { #[rename = "u"] Unit, One(i32), Two(i32, i32), Cmpx { a: i32, b: i32, #[rename = "z"] c: i32, }, }

fn main() { let s = Simple { n: 12.3, b: true }; println!("{}", s.to_json());

let n = Nest {
    a: vec![1.2, 2.3],
