List Management- Separating each list

Hi there,

I have been working on this 3D voronoi file and I stuck in this problem. As you see both in the attached image and explanatory GH file, I need to separate each sublist in a diiferent list. Right now, they all are in on list like:

{0,0}

{0,1} 

{0,2} 

{0,3} 

{1,0} 

{1,1}

{1,2}

{2,0}

{2,1}

but i want them to be like (exactly like before Deconstruct Brep panel):

{0,0}

{0,1} 

{0,2} 

{0,3} 

-----

{1,0} 

{1,1}

{1,2}

-----

{2,0}

{2,1}

Any body knows how should I do it?

I appreciate your help. Thanks
