Breaking Changes

BC-160	Manufacture simulation speed	The property Manufacture.SimulationSpeed now refers to the real speed of the end mill during the simulation, measured in world units per second.
BC-159	GetPointsForBb()	The Region.GetPointsForBb() method was renamed to Region.GetPointsForConvexHull()
BC-158	IFC properties	IfcMeasureValue and ifcPhysicalQuantity properties are now loaded as Tuple<string, double> with the unit type as the first item.
BC-157	OriginSymbol labels	Replaced OriginSymbol.LabelColor property with LabelColorName, LabelColorX, LabelColorY and LabelColorZ.
BC-154	Protobuf	Serializer.SetProtobufModel() method is now protected instead of public.
