/**
 * A Serializer for libGDX {@link Array} objects.
 * This was copied almost-directly from CypherCove's GdxToKryo repo.
 * This is not recommended for use from outside code, because it could be moved into a different project.
 * 

 * Unlike the original, this does not record the Class of items of an Array. That requires registering Object for most
 * Array instances, and I'm not sure if that's a good idea.
