        Add a sample WmtsLayer. Setting the 'ID' Property is good if you want to access the WmtsLayer in code-behind.
        It is mandatory that you set the correct 'ServiceMode' Property. Setting the 'InitializationFailed' Event is useful
        to troubleshoot if the WmtsLayer fails to load. A 'ProxyUrl' is needed to test this particular service; it is not
        always necessary depending on your configuration (i.e. local web service internal to your network). Use the 
        'Initialized' Method to gain access to various Properties/Methods of the WmtsLayer.
