#1 retvalue by reference require temp variable

[Alexey V. Vasilyev]

class Inteface {
public:
virtual QString& getValue() = 0
}

1. Required temp variable for correct transmitting to client code.
2. Need to use non refernced type for constructing return value holder.

must be generated:
...
QString getValue_retvalue;
virtual QString& getValue()
{
return getValue_retvalue = CXXMOCK_GET(QString )
}
