Oh noes! Yesterday it worked with the current trunk :D

I'll do it later, I'm currently in a lecture and the wlan does not permit the svn port :/

>   Original Estimate: 4h

> When profiling graph computations running on HAMA it turned out that huge amount of time
is spent in RPC calls.
> To reduce this overhead I propose extending the GroomServer's API with a put(BSPMessageBundle)
method so that a group of messages can be transferred from the caller to the callee at once.
Also, the sync() operation should be improved by sending messages in batches rather than one-by-one.
> Using BSPMessageBundle makes it easier to add support for compression of messages later.
