ang 0.2.0

Angular types and common helper methods.
Documentation 
# Ang

Ang is a fork of the [Angular](https://crates.io/crates/angular) crate to add various
improvements.

Angular types and common helper methods to work with them while using the [Rust]
type system in our favor.

## Features

* Tested and documented,
* Safety without sacrificing performance and conversion related errors,

## Usage

Everything evolves around the `Angle<T>` type and its two variants
`Degrees(v)` and `Radians(v)`. This ensures proper typing and allows for safe
helper methods evolving around it.

```rust
extern crate ang;

use angular::*;
use std::f64::consts::{SQRT_2, FRAC_PI_4};

fn calc_hypotenuse(opposite: f64, alpha: Angle) -> f64 {
    opposite / alpha.sin()
}

let a = calc_hypotenuse(SQRT_2, Radians(FRAC_PI_4));
let b = calc_hypotenuse(SQRT_2, Degrees(45.0));
let c = calc_hypotenuse(SQRT_2, Angle::eighth());

assert!((a - 2.0).abs() < 1.0e10);
assert!((a - b).abs() < 1.0e10);
```
