Hi Mitch,

according to the [Qt Docu](http://doc.qt.io/qt-5/qmetatype.html#qRegisterMetaType-1) ```qRegisterMetaType``` is (only) needed under some circumstances:

    To use the type T in QVariant, using Q_DECLARE_METATYPE() is sufficient. To use the type T in queued signal and slot connections, qRegisterMetaType<T>() must be called before the first connection is established.
    
To prevent complicated issues if we use queued connections ourself in the future the ```qRegisterMetaType``` should go somewhere else. I think it should be ```mymoneymoney.cpp``` for ```MyMoneyMoney``` but I am unsure here.
