Artem Pavlenko aed5516197 1. new feature model - based on boost::property_map concept
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
