/* plotWindow.h: Header file that defines the plotWindow structure. This
 * structure will be passed along with a Grid-structute to plotting

 * to only decide what is plotted from the data, which comes from a
 * Grid-structure. The function is also passed a plotWindow-structure so
 * it knows in which window are we supposed to plot. */
