Expedition PCB: Add a new user layer, or clean the layer if exists

Version 1

    This script is to add a new user layer to be prepared to add drawing or text to the layer.


    Before using Document.PutUserLayerGfx or Document.PutUserLayerText to add drawong or text, this code can be used to make sure if the user layer is prepared.


    The script will begin with a prompt dialog to enter the layer name to add, and add the user layer or (if the layer already exists,) remove all drawings/texts on the layer.


    Automation method to add a user layer requires saving PCB database, so I added the Document.Save statement after adding a user layer.
