Link with g++, *not* with gcc. gcc does not link in the standard

    these in automagicly.

 build : attribute.o element.o parser.o
 	g++ -c main.cpp -o obj/main.o
 	g++ -o test.out obj/Attribute.o obj/Element.o obj/Parser.o obj/main.o
 attribute.o :
 	g++ -c xml/model/Attribute.cpp -o obj/Attribute.o
 element.o : attribute.o
 	g++ -c xml/model/Element.cpp -o obj/Element.o
 parser.o : attribute.o element.o
 	g++ -c xml/parsers/Parser.cpp -o obj/Parser.o
