    This module call script 'roco_dsn.py' to generate a DSN file for auto_router. 
    An interface will pop up for the user to confirm wiring design,
    if a user does not want to change anything, one can just simply close the window.
    Routing information will be stored automatically in the same directory.
    The routing information will be read and draw the corresponding line on the dxf file

    (Please make sure the ME drawing has everything need to cut (obstacles) in "Cut" layer)
    
    Tested Python Version: 3.6

    path information needed:

    - mechanical design drawing file 
    - A csv file describes your netlist
    - modules library dir
    - dsnwritier(sesreader) dir
