parse_result 0.1.0

# Adds a `parse` method to `Result`

## Example

```rust,no_run
extern crate parse_result;
use parse_result::*;
use std::env;

fn main() {
    // It turns code like this:
    env::var("PORT").map(|s| s.parse().unwrap_or(3000)).unwrap_or(3000);

    // Into this:
    env::var("PORT").parse().unwrap_or(3000);

    // Matching to find the specific failure
    match env::var("PORT").parse::<u32>() {
        Ok(port) => println!("Parsed port {} successfully!", port),
        Err(OriginalErr(e)) => panic!("Failed to get PORT from env: {}", e),
        Err(ParseFailure(e)) => panic!("Failed to parse PORT: {}", e),
    }
}
```
