-// This is the implementation behind ref_list_of() and ref_copy_list_of().
-//
-// The motivation for this class was to improve upon ref_list_of<int>(), by 
-// deducing the number of arguments at compile time, and allowing for either 
-// of copy or rebind semantics, in case it is used as the lhs of an assignment; 
-// the former (copy) being both safer and more common than the latter (rebind).
-//    
-// Acknowledgement: The idea of this class was developed in collaboration 
-// with M.P.G
-//
-// Revision history:
-// Feb 9, 2010 : 
-// 	- Added copy semantics.
-// 	- The temporary array in the conversion operator is now assigned by calling 
-// 	begin() and end() rather than write_to_array() to ensure consistency of 
-//  side effect when assigning under rebind semantics. Negligible loss in 
-//	performance
-// Feb 5, 2010 : First version. rebind semantics.
