    Attachment: CRUNCH-519.diff

A proposed patch to add file size & number of reducers planned.
I tested it and it looks good :)

> The current plan dot file display nicely the jobs, with nice names and arrows.
> However it does not explain how the planner decided on the reducers number, which is
based on the input data size, scale factor and desired size per reducer.
> I suggest adding this information to the dot file.
> An addition to the DotfileWriter class can do this easily.
