- Added AvroXml and AvroXmlIO to map the scala.xml.Node scala type to the primitive Avro string type, tests for same.
- Removed premature calls to BinaryEncoder.flush from the internal AvroTypeIO.write methods.
- Added ReflectionHelpers.varargsFactory[T] for deriving a factory method by reflecting on the supplied type's companion (allows for more possibilities than a varargs apply method).  Added for the benefit of scala.xml.NodeSeq, which extends Seq[scala.xml.Node] but lacks a varargs apply.
- Added information about the new reflective factory method support for collections to the README
