Offset	Return Type	Name	Arguments	Description
IUnknown:
0x0	HRESULT	QueryInterface	REFIID iid void ** ppvObject	MSDN: "Returns a pointer to a specified interface on an object to which a client currently holds an interface pointer."
0x4	ULONG	AddRef	none	MSDN: "[...] increments the reference count for an interface on an object. It should be called for every new copy of a pointer to an interface on a given object."
0x8	ULONG	Release	none	MSDN: "Decrements the reference count for the calling interface on a object. If the reference count on the object falls to 0, the object is freed from memory."
IPersist:
0xC	HRESULT	GetClassID	CLSID * pClassID	MSDN: "Retrieves the class identifier (CLSID) of an object. The CLSID is a unique value that identifies the code that can manipulate the persistent data."
IPersistStream:
0x10	HRESULT	IsDirty	none	MSDN: "Checks the object for changes since it was last saved."
0x14	HRESULT	Load	IStream* stream AbstractClass* dst	MSDN: "Initializes an object from the stream where it was previously saved."
0x18	HRESULT	Save	IStream* stream AbstractClass* src (3rd is unknown)	MSDN: "Saves an object to the specified stream."
0x1C	HRESULT	GetMaxSize	ULARGE_INTEGER * pcbSize	MSDN: "Returns the size in bytes of the stream needed to save the object."
AbstractClass:
0x20	none (DTOR)	Destructor	none	Frees memory and removes this instance from global arrays.
0x24	unknown	unknown	unknown
0x28	unknown	unknown	unknown
0x2C	int	GetAbstractDerivationID	none	Gets the AbstractDerivationID of this class. Used to find out "what something is".
0x30	int	GetSize	none	Gets the size of the member data.
0x34	unsigned long	GetCRC	unknown	Calculates a CRC sum of this instance.
0x38	int	GetOwningHouseIndex	none	Gets the index of the House (player) who owns this object.
0x3C	HouseClass*	GetOwningHouse	none	Gets a pointer to the House (player) who owns this object.
0x40	int	GetArrayIndex	none	Gets the index of this class instance in the global array. This will return 0 for abstract classes.
