Rectangle shapes

[Karpyshyn]

Your code is not working correctly for rectangle shapes with 4 points.
Try first this coordinates
var coords = [
{'lat' : '50.157913235507706', 'lon' : '29.900512524414125'},
{'lat' : '50.74029471119741', 'lon' : '31.146087475586'},
{'lat' : '50.74029471119741', 'lon' : '29.900512524414125'},
{'lat' : '50.15791323550770611', 'lon' : '31.146087475586'}

];

var centrePoint = new google.maps.LatLng(50.5, 30.0);

This example works incorrectly

And than change a little last point lat. F.e.
{'lat' : '50.17791323550770611', 'lon' : '31.146087475586'}

This one is good

Just change
if (this.reverse){
if (angle > 0) {
angle += 360;
}
}else{
if (angle < 0) {
angle += 360;
}
}

To
if (this.reverse){
if (angle >= 0) {
angle += 360;
}
}else{
if (angle <= 0) {
angle += 360;
}
}

@Karpyshyn Thank you for the bug report, very much appreciated! I've pushed the change and added a 4th example and test.
Thanks again!
