	Default method used by the __tostring metamethod to capture the result of tostring() over an object.
Protected Attributes inherited from GmLuaObject
const GmLogCategory &	_logger
	A logger used by the proxy when needed.
QAtomicInteger< int >	_refCount
	Lua objects are reference counted to enable sharing them among different states. This is needed to allow for passing objects as parameters in a parallel call. The garbage collection method releases memory only for the last reference.
