readGeometryTaggedText method
Creates a Geometry
using the next token in the stream.
@return a Geometry
specified by the next token
in the stream
@throws ParseException if the coordinates used to create a Polygon
shell and holes do not form closed linestrings, or if an unexpected
token was encountered
@throws IOException if an I/O error occurs
@param tokenizer tokenizer over a stream of text in Well-known Text
