+/**
+ * \brief a polymophic address class
+ *
+ * This class is very similar in design and spirit to the BSD sockaddr
+ * structure: they are both used to hold multiple types of addresses
+ * together with the type of the address.
+ *
+ * A new address class defined by a user needs to:
+ *   - allocate a type id with Address::Register
+ *   - provide a method to convert his new address to an Address 
+ *     instance. This method is typically a member method named ConvertTo:
+ *     Address MyAddress::ConvertTo (void) const;
+ *   - provide a method to convert an Address instance back to
+ *     an instance of his new address type. This method is typically
+ *     a static member method of his address class named ConvertFrom:
+ *     static MyAddress MyAddress::ConvertFrom (const Address &address);
+ *   - the ConvertFrom method is expected to check that the type of the
+ *     input Address instance is compatible with its own type.
+ *
+ * Typical code to create a new class type looks like:
+ * \code
+ * // this class represents addresses which are 2 bytes long.
+ * class MyAddress
+ * {
+ * public:
+ *   Address ConvertTo (void) const;
+ *   static MyAddress ConvertFrom (void);
+ * private:
+ *   static uint8_t GetType (void);
+ * };
+ *
+ * Address MyAddress::ConvertTo (void) const
+ * {
+ *   return Address (GetType (), m_buffer, 2);
+ * }
+ * MyAddress MyAddress::ConvertFrom (const Address &address)
+ * {
+ *   MyAddress ad;
+ *   NS_ASSERT (address.CheckCompatible (GetType (), 2));
+ *   address.CopyTo (ad.m_buffer, 2);
+ *   return ad;
+ * }
+ * uint8_t MyAddress::GetType (void)
+ * {
+ *   static uint8_t type = Address::Register ();
+ *   return type;
+ * }
