Constructs and deconstructs Configuration values.

A configuration is constructed by first specifying required attributes via Configuration() and then attaching optional attributes as necessary. A set of implicit methods conveniently convert between instances of Configuration and Builder.

Example:

val config = Configuration {
  ("foo.server.com", 2181) :: ("bar.server.com", 2181) :: Nil
} withTimeout {
  60 seconds
} withWatcher { (event, session) =>
  // ...
}

The type of config above is Builder since an implicit conversion occurred when attaching optional attributes using the various with methods. An explicit conversion back to Configuration, which can be accomplished using build(), is unnecessary since another implicit will perform this function automatically.
