Rust Derive Macro for D3 -- A Framework for Server Development

Custom derive for automatically implementing the MachineImpl trait for an enum, tranforming it into a d3 instruction set. d3-derive is a companion to d3-core and d3-components. Combined, they form a framework for server development.

```rust

[macro_use]

extern crate d3_derive;

[derive(MachineImpl)]

pub enum Foo { Bar, Baz { name: String, }, Baa (u32), } ```
