Intro to WCSLayer

This sample shows how to add an instance of WCSLayer to a Map in a MapView. The WCSLayer contains global sea temperature data.

The RasterStretchRenderer is applied to the layer to change the data visualization. The multidimensionalDefinition property is also set on the layer to request a specific slice.
