Scala-IO Core: Seekable

At the same level of abstraction as Input and Output is the fine trait called Seekable.  As the name implies it provides random access style methods for interacting with a resource.  The example that comes immediately to mind is a random access file.

The design of Seekable largely mimics the scala.collection.Seq patch and insert methods.  Not much more to say beyond getting into some examples:
IMPORTANT: Each time truncate() or patch or insert is called a new connection to the file is opened and closed. The Processor API is to be used to perform multiple operations within one connection.
