Overview

Add some sugar to the MarcWriter interface

Adjust the interface so that a #new call to any implementations that implement it can take a java.io.InputStream, ruby IO object, or String (that will be interpreted as a filename) without complaining.

The mechanism -- running module_eval on a string-representation of the new method in each of the hard-coded implementations -- is ugly and deeply unsettling.
