** Class: SerializationFieldInfo 
**
** 
** Purpose: Provides a methods of representing imaginary fields
** which are unique to serialization.  In this case, what we're
** representing is the private members of parent classes.  We
** aggregate the RuntimeFieldInfo associated with this member 
** and return a managled form of the name.  The name that we
** return is .parentname.fieldname
