Creates a new Ruby object from XML using mapping information annotated in the class.
The input data is either an XML::Node, String, Pathname, or File representing the XML document.
Example
book = Book.from_xml(File.read("book.xml"))
or
book = Book.from_xml("<book><name>Beyond Java</name></book>")
initialization_args passed into from_xml will be passed into the object’s .new, prior to populating the xml_attrs.
