Class Writer

Method Summary
`Writer` | `leftShift(Object value)` Overloads the left shift operator to provide a mechanism to append values to a writer.
`PrintWriter` | `newPrintWriter()` Create a new PrintWriter for this file, using specified charset.
`Object` | `withPrintWriter(Closure closure)` Create a new PrintWriter with a specified charset for this file.
`Object` | `withWriter(Closure closure)` Allows this writer to be used within the closure, ensuring that it is flushed and closed before this method returns.
`void` | `write(Writable writable)` A helper method so that dynamic dispatch of the writer.write(object) method will always use the more efficient Writable.writeTo(writer) mechanism if the object implements the Writable interface.
