New class dialog improvements

There are a few improvements I believe that should be made to the new C++ class dailog

1. It would be nice to be able to specify a base class name to inherit and designate the header that contains it.
For example, suppose I have a class Derived that I want to inherit from Base. It would be nice to designate the header "base.h" so that the boiler-plate code supplied when the dialog was finished would include

#include "base.h"

2. When a base class is specified, it would be nice if ( at least ) all of the pure virtual functions from the base class were included in the boiler-plate header file:

//base.h
class Base
{
    Base();
    virtual ~Base();
    virtual function0() = 0;
    virtual function1();
};
//derived.h   supplied as boiler-plate
#include "base.h"
class Derived : public Base
{
    Derived();
    virtual ~Derived();
    virtual function0 = 0;  /// @note pure virtual function defined in Base class
    virtual function1();  /// @note virtual function defined in Base class
};

It would also be nice to be able to specify mutliple classes from which to inherit.

Thanks for your time!
