Short description:	Module to send data to METKMsgReceiver for synchronized message handling

Usage

Module to send data to METKMsgReceiver. There must be only one receiver listening to the same message! For more general information, have a look into Section 6.

If there is no responsible receiver for a message, the transmission is canceled. Otherwise, the message will be send. After processing, METKMsgSender will be informed whether the data was handled. No further information can be sent back to the sender.

Known problems

The behavior is of the messaging modules is undefined when there is more than one METKMsgReceiver for one message!
