Usage

Encode Points:

var polyliner = new Polyliner();
var points = new List<PolylinePoint> 
{
    new PolylinePoint(latitude: 52.22778, longitude: 20.98614), 
    new PolylinePoint(latitude: 52.22555, longitude: 20.98725)
};

var result = polyliner.Encode(points); 

Console.WriteLine(result); // "svw}Hkza_C|L}E"

Decode Polyline:

var polyliner = new Polyliner();
var polyline = "svw}Hkza_C|L}E";

var result = polyliner.Decode(polyline);

Console.WriteLine(result[0].Latitude.ToString("0.00000", CultureInfo.InvariantCulture));  // "52.22778"
Console.WriteLine(result[0].Longitude.ToString("0.00000", CultureInfo.InvariantCulture)); // "20.98614"
Console.WriteLine(result[1].Latitude.ToString("0.00000", CultureInfo.InvariantCulture));  // "52.22555"
Console.WriteLine(result[1].Longitude.ToString("0.00000", CultureInfo.InvariantCulture)); // "20.98725"
