Improve exception safety with smart pointers

[elfring]

Would you like to wrap any pointer data members with the class template “std::unique_ptr”?

Good suggestion, but I don't care.

The Code of this utility is very simple and not required smart pointers.
If you want to change raw pointers to the smart pointer, make a pull request and use the QSharedPointer instead of the std::unique_ptr, because the unique_ptr works only with move semantic and not calculate references count to an object.

In this case, object are passed into constructors other inner objects of main class. So you should be use QSharedPointer.

I assign this issue to you.
So if you want help project, move it to smart pointers.
