ChangeStyle
When you enter the ChangeStyle command on the Map command-line, you cause an instance of the Implementation class to be created and its ChangeStyle method to be executed.
The ChangeStyle method gets the current map, gets the layers in the current map, loops through the layers until it finds the layer containing the buffered features and then calls the ChangeSurfaceLayerStyle method with the buffered features layer as an argument.
The ChangeStyle method changes the color of the buffered features layer in the current map. This is described in topic ChangeSurfaceLayerStyle.
