Ini parser for Rust
```no_run
use ini::Ini;
let mut conf = Ini::new();
conf.with_section(Some("User"))
.set("name", "Raspberry树莓")
.set("value", "Pi");
conf.with_section(Some("Library"))
.set("name", "Sun Yat-sen U")
.set("location", "Guangzhou=world");
conf.write_to_file("conf.ini").unwrap();
let i = Ini::load_from_file("conf.ini").unwrap();
for (sec, prop) in i.iter() {
println!("Section: {:?}", sec);
for (k, v) in prop.iter() {
println!("{}:{}", k, v);
}
}
```
