ClaimSet provides methods to manually validate individual claims.
```
try claims.validateAudience("example.com")

2.0.1

This release adds support for Swift 3.0.

Breaking

Algorithms now take Data instead of a String. This improves the API allowing you to use keys that cannot be serialised as a String.

You can easily convert a String to Data such as in the following example:
```
.hs256("secret".data(using: .utf8)!)
```

1.5.0

This release updates the dependency on CryptoSwift to ~> 0.4.0 which adds support for Swift 2.2.
