subplot and subplot! are distinct commands which create many plots and add series to them in a circular fashion.
You can define the layout with keyword params... either set the number of plots `n` (and optionally number of rows `nr` or
number of columns `nc`), or you can set the layout directly with `layout`.
Note: Gadfly is not very friendly here, and although you can create a plot and save a PNG, I haven't been able to actually display it.
