/** 
* @file  Platform/Aperios1.3.2/UDPHandler.h
*
* Class for using NetSender/NetReceivers over UDP 
*
* @author <A href=mailto:robocup@m-wachter.de>Michael Wachter</A>
*
*
* The UDP-Handler sends data from NetSender's via an UDP based Protocol.
* If the data from the NetSender, the package, is too big for one
* UDP-Package (1500 bytes) the data is split into "subpackets".
* Each of this subpackets has the same packageNumber, an increasing
* subPackageNumber, the complete size and the data itself. (not implemented yet)
* With this information the receiving robot can put the data together into
* the right order and can find out package-loss.
* If the complete package is received the associated NetReceiver is called
* to stream the data.
