Frequency Unit
====================

A library for interaction with units of frequency.

## Example

```rust
let freq = Frequency::from_mhz(1.0);
let freq2 = Frequency::from_mhz(2.0);
let freq3 = freq + freq2;

let a: f64 = freq3.to_mhz();

assert_eq!(a, 3.0);


let freq = Frequency::from_mhz(12.3456789);

assert_eq!(format!("{:<10.2}", freq), "12.35     MHz");
```
