Testing constructors

An alternative to the constructor that uses pointers is creating and exporting a VI that provides a valid, non-initialized class reference which will be initialized in the Create.vi.
This proved very useful in a situations where you cannot use the .NET FormatterServices GetUninitializedObject Method of mscorlib.dll to instantiate a new object without calling its constructors.
