1. Removed srid from geometry class

Browse source 
2. Pass resolution to bbox query
3. Use variant<int,double,string> as parameter value e.g in Python:
	ds = Raster(file="/path/to/file",lox = 12312.4,.....)
   Added extractor facility to work with mapnik::parameter (C++):
	
	mapnik::parameters params;
	params["parameter0"] = 123.456;
	params["parameter1"] = "123.456"; // initialize with string extract double later
	
	boost::optional<double> val0 = params.get<double>("parameter0");
	if (val0) 
	{
	   std::cout << *val0;
        }
	
	
	// with default value. NOTE: there is no 'parameter2' in params
	boost::optional<double> val2 = params.get<double>("parameter2",654.321);
	std::cout << * val2;
        
	// 
4. Added Gdal factory method in __init__.py

        ds =  Gdal(file="/tmp/file.tiff")
