Class IFCWBeta

IFC building models as reached from a script: every method of the ifc worker, asynchronous, with models living in the worker and passed around as references, plus geometry.toShapes, geometry.toDocument and geometry.toStep, which build a model's elements with OpenCascade. In Node, or anywhere without workers, the IFC package's IFCService has the same methods, synchronous and with models as values; there those three are geometry.recipe handed to the OpenCascade kernel's recipes.build or recipes.buildDocument. Experimental, as the IFC library is.
