public class Converter
A mutation for converting an old version of an object value to conform to the current class or field definition. For example:
  package my.package;
  // The old class.  Version 0 is implied.
  //
  @Entity
  class Person {
      // ...
  }
  // The new class.  A new version number must be assigned.
  //
  @Entity(version=1)
  class Person {
      // Incompatible changes were made here...
  }
  // Add a converter mutation.
  //
  Mutations mutations = new Mutations();
  mutations.addConverter(new Converter(Person.class.getName(), 0,
                                       new MyConversion()));
  // Configure the mutations as described here.
