This is a config file reader for Iron framework(an web framework writen in Rust).

You can put all you settings in a file which names Iron.toml.

## It will search Iron.toml by this order:

2, `./Iron.toml`

3, `./site/Iron.toml`

## Usage:
In you Cargo.toml:

```toml
    [dependencies]
    iron_config = "0.1.0"
    lazy_static = "*"
```
In you crate:

```rust
    extern crate iron_config;
    use iron_config::IC;
    #[macro_use]
    extern crate lazy_static;
    lazy_static!{
       static ref DOMAIN: &'static str = IC.lookup("MAIN.DOMAIN").unwrap().as_str().unwrap();
     }

    fn main() {
        println!("{:?}",*DOMAIN); 
    }
