Aurora tutorial generator

Square

LICENCE : CC
Sam Neurohack


2 Cases : 

1/ You generate one points position (x,y,z) list, like a one color square and send it back to Aurora that will add color, move your points,...
    cf code Case 1

2/ You need several points positions lists with different parameters like colors,...
    cf code Case 2

    You need to use as much as primitive drawing functions you need :

        - PolyLineOneColor, rPolyLineOneColor, LineTo, Line
        - PolyLineRGB, rPolyLineRGB, LineRGBTo, LineRGB 
        - Text(word, integercolor, layer , xpos, ypos, resize, rotx, roty, rotz) : Display a word
        - TextRGB(word, red, green, blue, ...)

Your function get a LAY argument 

Layer properties from current UI. But you can use your numbers
