the base class when computing the length of the derived class.
class of a Srtructure or Union derived subclass when cloning or modifying the _fields_ array. The old behavior of using the number of elements in the parent class can cause the array to be truncated when it is copied, especially when there are multiple layers of subclassing. Tests are included.
Now StgDictObject.length of Structure and Union is the number of all fields, including fields of superclases.
