plugin to create a Cesium terrain provider from Geoserver

#Example
```
var terrainProvider = new Cesium.GeoserverTerrainProvider({
			service: "TMS",	
	        url : "http://localhost:8080/geoserver/elevation/wms",
	        layerName: "SRTM90",
	        xml: xmlGetCapabilities,
	        proxy: proxy,
	        heightMapWidth: 64,
          heightMapHeight: 64,
	        offset: 0,
	        highest: 12000,
	        lowest: -500,
	        styleName: "grayToColor",
	        hasStyledImage: true
	        maxLevel: 11
	    });
```
	    
#Details
For the example the workspace in geoserver is "**elevation**", the layer name is "**SRTM90**", the url of geoserver is "**geoURL**" and the name of style is "**grayToColor**".
