README

        
There are three ways to declare object: use (just) object, use object in QScopedPointer or object in std::unique_ptr.

```

    class1 cl1;

    std::unique_ptr cl2(new class1());

    QScopedPointer cl3(new class1());

    QBuffer buffer;

    buffer.open(QIODevice::WriteOnly);

    QDataStream myStream(&buffer);

    myStream << cl1 << "    " << *cl2.get() << "    " << *cl3.get();

    qDebug() << buffer.data();

```

output

```

"\x00\x00\x00\x0E\x00""d\x00""e\x00""f\x00""a\x00u\x00l\x00t\x00\x00\x00\x05    \x00\x00\x00\x00\x0E\x00""d\x00""e\x00""f\x00""a\x00u\x00l\x00t\x00\x00\x00\x05    \x00\x00\x00\x00\x0E\x00""d\x00""e\x00""f\x00""a\x00u\x00l\x00t"

```

## Features

class1 contains private field but operator overloading containd `friend` keyword to accsess to private field.
