WIP: Layers split into islands, islands overlapping in Z interconnected

Browse source 
into a graph with links to the layer above / below.

In addition:
Members of LayerRegion were made private, public interface const only.
this->m_xxx replaced with just m_xxx
SurfacesPtr was made a vector of const pointers.
