+ * \brief PDU wrapper that caches the result of the wrapped PDU's 
+ * serialization.
+ * 
+ * This wrapper class holds a PDU of the template parameter type, and
+ * forwards every PDU virtual call to the stored object. Whenever a
+ * call to write_serialization is performed on this wrapper, the result
+ * is cached in a PDU::serialization_type. On subsequent calls to
+ * PDUCacher::write_serialization, the contents of that cache will be
+ * written to the output buffer.
+ * 
+ * This class should provide a nice performance boost if you're sending
+ * over and over a packet that requires some computation while being
+ * serialized, such as performing checksums, iterate and copy options,
+ * etc.
