/** \brief Macro that adds <<std member comp>> attributes to any class
*
* For example, if you want to include a <<std member comp>> attribute
* as a member object of type MyClass with the name my_attribute you
* would include the macro in the public section of YourClass
* declaration as follows:
\verbatim
class YourClass {
public:
STANDARD_MEMBER_COMPOSITION_MEMBERS( MyClass, my_attribute );
};
\endverbatim
* This macro adds the following data member to the class declaration:
\verbatim
private:
MyClass my_attribute_;
\endverbatim
* and the following methods to your class declaration:
\verbatim
public:
void my_attribute( const My_Class & my_attribute_in )
{ my_attribute_ = my_attribute_in; }
const My_Class& my_attribute() const
{ return my_attribute_; }
\endverbatim
* The advantage of using this type of declaration is that it saves
* you a lot of typing and space. Later if you need to override these
* operations you can just implement the member functions by hand.
