Derive Display trait for enums

This crate can derive a Display implementation for very simple enums, like the following one:

```rust

[macro_use]

extern crate enumdisplayderive;

use std::fmt::Display;

[derive(Display)]

enum FizzBuzz { Fizz, Buzz, FizzBuzz, Number(u64), }

fn fb(i: u64) { match (i % 3, i % 5) { (0, 0) => FizzBuzz::FizzBuzz, (0, ) => FizzBuzz::Fizz, (, 0) => FizzBuzz::Buzz, (_, _) => FizzBuzz::Number(i), } }

fn main() { for i in 0..100 { println!("{}", fb(i)); } } ```
