    Example
    Customizing the Sketch Symbol of a Custom Sketch Tool
    //Custom tools have the ability to change the symbology used when sketching a new feature. 
    //Both the Sketch Segment Symbol and the Vertex Symbol can be modified using the correct set method. 
    //This is set in the activate method for the tool.
