// layer 1 - layer that routes member access through the access class.
// this is what permits us to grant access to private class member functions
// by specifying friend class boost::serialization::access

// layer 2 - default implementation of non-intrusive serialization.
//
// note the usage of function overloading to compensate that C++ does not
// currently support Partial Template Specialization for function templates 
// We have declared the version number as "const unsigned long".  
// Overriding templates for specific data types should declare the version
// number as "const unsigned int". Template matching will first be applied
// to functions with the same version types - that is the overloads.  
// If there is no declared function prototype that matches, the second argument
// will be converted to "const unsigned long" and a match will be made with 
// one of the default template functions below.

// layer 3 - move call into serialization namespace so that ADL will function
// in the manner we desire.
//
// on compilers which don't implement ADL. only the current namespace
// i.e. boost::serialization will be searched.

// serialize overrides can be in any of the following
// 
// 1) same namepace as Archive
// 2) same namespace as T
// 3) boost::serialization
