Citations - bp:AUTHORS are deleted

[larsgw]

I get that the TITLE, YEAR, SOURCE, and AUTHORS are on their way out, but for now, editing GPML 2013a, it seems like bp:AUTHORS elements are always deleted. Looking at the code I see this:

pathvisio/modules/org.pathvisio.core/src/org/pathvisio/core/model/GpmlFormat2013a.java

Lines 842 to 853 in 33d315b

	// now sort the generated elements in the order defined by the xsd
	Collections.sort(elementList, new ByElementName());
	for (Element e : elementList) {
	// make sure biopax references are sorted alphabetically by rdf-id
	if(e.getName().equals("Biopax")) {
	for(Element e3 : e.getChildren()) {
	e3.removeChildren("AUTHORS", GpmlFormat.BIOPAX);
	}
	e.sortChildren(new BiopaxAttributeComparator());
	}
	root.addContent(e);
	}

Removing the inner for loop fixes the issue. Why was this introduced (83b82e4)?
