== Wrapper construction ==

app --> qobjectts: new()
activate qobjectts
qobjectts --> qobjectwrap: new()
activate qobjectwrap
qobjectwrap --> qobject: new()
activate qobject
qobject --> qobjectwrap: QObject instance

qobjectwrap --> wrappercachecpp: store(QObject, QObjectWrap)
wrappercachecpp --> qobject: connect to destroy signal

qobjectwrap --> qobjectts: QOjectWrap instance
qobjectts --> wrappercachets: store(QObject.ts)
qobjectts --> app: QObject instance


note across: The app can use the QObject and run.
