Malfunctioned `IStorable.Store` crashes Rhino

Serengeti (Rhino WIP) Grasshopper2

Put the following code in a Component's Store method. Add the component into document and remove it. Rhino will crash.

I think GrasshopperIO should catch all exceptions.

        public override void Store(IWriter writer)
        {
            base.Store(writer);
            throw new NullReferenceException();
        }

FATAL UNHANDLED EXCEPTION: System.NullReferenceException: 未将对象引用设置到对象的实例。

Eventually yes, but for the time being I want to find all the places where exceptions are thrown during serialisation.
