Parent layers to vertex

Question

Hello,
Although I've found way and scripts to parent mask vertices to objects, I've been unsuccessful if creating the reverse.
I'm fairly new at this but not new to programming.
What I would like my this script to achieve:
     Making a layer mask at the corners of a layer - check
     Creating 4 nulls - check
     Parenting the nulls to the 4 corners -
For creating the mask I have this:
     var myShape = new Shape();
     var vertices = new Array ();
     myShape.vertices = [[0,0], [0,100], [100,100], [100,0]];
     var myProperty = theMaskGroup.property("ADBE Mask Shape");
     var vertexLimit = myShape.vertices.length;
For creating the nulls:
     function Nulls (){
     for (var i = 0; i < vertexLimit; i++){
        theNull = theComp.layers.addNull();
        theNull.source.name = "Null"+(i+1);
        i+1;
        nulls[i] = theNull;
When it comes to moving/parenting nulls to mask verts I am completely lost.
Any help would be much appreciated.
Thank you

Hi chillywilson,
As far as I know, by default you can`t just parent any property to mask vertices.
But you can do it in two ways:
break mask vertices to Nulls and then parent anything to them.
          This script has this function:

There is also a plugin that represents mask vertices as effect properties:
