Sequence diagram for scheduling algorithm

[FellowPlanter]

Must describe what happens after a job is sent to the central server, and before it is sent to a work machine.

(Like @JohannesGaessler said, the Snelting document recommends starting with sequence diagrams in order to get a better understanding of the classes and packages required for the project. So we should probably start with them.)

I played with plantuml today and made this, but I don't think it is very good and I got a bit confused.

@nikolatzotchev if you have started working on this, assign yourself.

But I'm not really sure I understand everything correctly, I was just testing stuff.

This isn't a sequence diagram for the scheduler though, it describes how a job is sent to the central server, that's another issue.
