// Generic Field Handles

/// \addtogroup GenericFieldHandles
///             Generic field handle classes, used to reference and work
///             with record members in a flexible, indirect way.
///
///             There are two ways to access device record data.  The obvious
///             way is to instantiate a record class, such as Contact, and
///             access the public data members of that class to read and
///             write.  If you always work with the same record class, this
///             works fine.
///
///             The other way is to have a list of pointers to members.
///             For example, you may wish to compare two records, without
///             actually caring what data is in each one.  You can compare
///             at the record class level, with Contact one, two; and then
///             if( one == two ), but this will not tell you what field in
///             the record changed.
///
///             This last feature is what Generic Field Handles are meant to
///             fix.  Each record class will contain a GetFieldHandles()
///             member function, which will return a vector of FieldHandle<>
///             objects, for that specific record.  For example, Contact
///             would fill a vector with FieldHandle<Contact> objects.
///             Each FieldHandle<> object contains a C++ pointer-to-member,
///             which the FieldHandle refers to, as well as a FieldIdentity
///             object.  The FieldIdentity object contains various identitying
///             information, such as the C++ variable name, an English
///             (or localized language) display name of the field, suitable
///             for user prompts, and other data more useful to the library.
///
///             The FieldHandle<> object has two member functions: Value()
///             and Member().
///
///             Value() will call a callback function with the _value_ of
///             the variable that FieldHandle<> points to.  For example,
///             if the FieldHandle<> points to a std::string record member
///             variable, then Value() will pass that string value in as
///             an argument, along with a reference to the FieldIdentity
///             object.  Value() requires a callback object and a record
///             object to perform this callback.
///
///             Member() will call a callback function/functor with the
///             pointer-to-member pointer and the FieldIdentity object.
///             This allows the programmer to create a functor with multiple
///             record objects, perhaps two objects to compare individual
///             fields, and use the pointer-to-member to access the field
///             data as needed.
///
///             For now, all data and callbacks are const, meaning that it
///             is not possible (without const_casting) to write to the
///             record via the pointers-to-members.  This design decision
///             may need to be revisited someday, depending on its usefulness.
