  end
end

#get_length(point_index) ⇒ Object

This method must determine the length of the given point to the next point in the polygon list. If the point is the last point, then it will be the distance from the last point to the first. point_name is the string named keyword in the keyword pair list. Example: “DOEPolygon 2” = POLYGON

V1               = ( 0, 0 )
V2               = ( 0, 1 )
V3               = ( 2, 1 )
V4               = ( 2 ,0 )

get_length(3) should return “2” get_length(2) should return “1”
