AECSmartReference Methods

	Name	Description
	createPathNode	Creates eSimple or eBlock reference for AECDbBlockRefPath (idBlockReference should be id of OdDbBlockReference )
	createSimple	Creates a simple reference (idObj should be from the database where the reference will be used )
	createWithPath	Creates an eBlockReference or eXRef reference with a path (idPath should be from the database where the reference will be used (not an XREF one!), idObj can be in the same database (eBlockReference) or in XREF ) Returns null reference, if the the path and the object do not match
	getPathId	Returns AECDbBlockRefPath object id, if the path is present
	getTargetId	Returns object ID of referenced object. Returns null id, if target id can`t be obtained (e.g. XREF was not loaded )
	getTransform	Returns product of blockTransform()s of all block references in this path.
	isNull	Returns whether this reference is null regardless of type.
	isValid	Returns true, if this reference points to a valid object and all intermediate references are valid.

AECSmartReference Operators

	Name	Description
	!=	This is !=, a member of class AECSmartReference.
	==	This is ==, a member of class AECSmartReference.
