commit 6c98193214e9459a5ded09c4e724cd724c059547
Author: Daniel Espinosa <esodan gmail com>
Date: Fri Nov 1 13:48:40 2013 -0600
Added Node.copy(). More Unit Tests.
* Added Node copy method, Element and Attr implementations too.
* Fixed unknown attributes de/serialize () for SerializableObjectModel
* All unknown properties are serialized back again to original file, to
avoid data lost on de/serialize operation
* Fixed issue with Element content text, using Text node representation
* Added unit test for unknown properties de/serialize
* Added unit test to avoid serialize properties set to null
