Shrink Vertex Selection

Installation: Copy the .ms file to your scripts\startup folder or run as a script if you only want to try it out. If you want to be able to use it from the modifier sets panel, place the .ms file instead inside the stdplugs/stdscripts folder in the 3ds max root folder. Upon running, the modifier will be available in the modifier stack. If you put it inside the stdscripts folder before evaluating it, you can add it to a modifier set for easier accessibility.
