Evaluation of configuration flags, at runtime-time.

## Usage

To use `runtime_cfg` in your project, add the following to your Cargo.toml:

``` toml

[dependencies]

runtime-cfg = "0.1"

```

## Example

```rust

use std::convert::TryFrom;

use quote::quote;

use runtime_cfg::*;

let cfg = quote! { #[cfg(all(unix, target_pointer_width = "32"))] };

let cfg = Cfg::try_from(cfg).unwrap();

assert_eq!(cfg, all(vec![name("unix"), name_value("target_pointer_width", "32")]).into());

let flags = vec![("unix", None), ("target_pointer_width", Some("32"))];

assert!(cfg.matches(&flags));

```
