f = feature(id);
f["name"] = "what is my name?";
boost.put(f,"area",123123.4325);
2. simplified and corrected value class and operators
3. updated input plug-ins to work with new features
4. add text_symbolizer (getting there:)
5. template version of agg_renderer
6. attribute_collector how accepts rules
(to collect attribute names for text labels)
