 Ficus adds an `as[A]` method to a normal [Typesafe Config](http://lightbend.github.io/config/latest/api/com/typesafe/config/Config.html) so you can do things like `config.as[Option[Int]]`, `config.as[List[String]]`, or even `config.as[MyClass]`. It is implemented with type classes so that it is easily extensible and many silly mistakes can be caught by the compiler.
