 - wip in adding Exclusion areas in Geometry object; each Geometry object has now a storage for shapes (exclusion shapes, should I make them more general?)
-- changed the above: too many shapes collections and the performance will go down. Created a class Exclusion areas that holds all the require properties and the Object UI elements will connect to it's methods. This way I can apply this to Excellon object too (who are a special type of Geometry Object)
