* SebmGoogleMapPolygon renders a polygon on a {@link SebmGoogleMap}

* ```typescript
* import { Component } from '@angular/core';
* import { SebmGoogleMap, SebmGooglePolygon, LatLngLiteral } from 'angular2-maps/core';
*
* @Component({
* selector: 'my-map-cmp',
* styles: [`
* .semb-map-container {
* height: 300px;
* }
* `],
* template: `
* <semb-map [latitude]="lat" [longitude]="lng" [zoom]="zoom">
* <semb-map-polygon [paths]="paths">
* </semb-map-polygon>
* </semb-map>
* `
* })
* export class MyMapCmp {
* lat: number = 0;
* lng: number = 0;
* zoom: number = 10;
* paths: Array<LatLngLiteral> = [
* { lat: 0, lng: 10 },
* { lat: 0, lng: 20 },
* { lat: 10, lng: 20 },
* { lat: 10, lng: 10 },
* { lat: 0, lng: 10 }
* ]
* // Nesting paths will create a hole where they overlap;
* nestedPaths: Array<Array<LatLngLiteral>> = [[
* { lat: 0, lng: 10 },
* { lat: 0, lng: 20 },
* { lat: 10, lng: 20 },
* { lat: 10, lng: 10 },
* { lat: 0, lng: 10 }
* ], [
* { lat: 0, lng: 15 },
* { lat: 0, lng: 20 },
* { lat: 5, lng: 20 },
* { lat: 5, lng: 15 },
