/**
* This class is used to make constructive solig geometry for items
* objects on layers.
* The operation is in the form (A - B) /\ C
* For almost all of the layers it translate something like:
* A (a via, a track, pad, polygon), B (a via hole, a THT hole, .. ),
* C the board (epoxy)
* For layers like Solder mask that are negative:
* A ( epoxy ), B( pads, polygons, ..), C=1
*
* Some notes:
* BODY = PCB_outlines - PCB_holes - (Modules_THT_holes + VIA_THT_holes)
*
* Plated_vias_and_holes = Tracks.Vias + Modules.PlatedHoles
*
* Layer.cu = ( Tracks.cu + Modules_Pads.cu + Modules_Graphics.cu +
* Layer_zones.cu + PCB_drawings.cu - Layer_VIA_holes ) & BODY
*
* Layer.Mask = BODY -
* (PCB_drawing.Mask + Modules_Graphics.Mask +
* Modules_Pads.Mask + Layer_zones.Mask )
* Layer.Paste = (PCB_drawing.Paste + Modules_Graphics.Paste +
* Modules_Pads.Paste + Layer_zones.Paste) & BODY
* Layer.Silk = (PCB_drawing.Silk + Modules_Graphics.Silk +
* Modules_Pads.Silk + Layer_zones.Paste) & BODY
*
* BODY = A - B /\ 1
* Layer.cu = A - B /\ C
* Layer.mask = A - B /\ 1
* Layers.Paste = A - 0 /\ C
* Layers.Silk = A - 0 /\ C
*
* BODY = P - T /\ 1
* Layer.cu = T - H /\ BODY
* Layer.mask = BODY - M /\ 1
* Layers.Paste = P - 0 /\ BODY
* Layers.Silk = S - 0 /\ BODY
