particular types of plots can inherit from this class. For instance,
sPlotView, is a class that inherits from plotView and represents a
scatterplot view.

Also, all classes that inherit from plotView will have clickEvent and
motionEvent methods. The clickEvent method will be called whenever a user
clicks on the plot and the motionEvent method will be called whenever a user
moves the cursor over the plot. These methods will be defined in packages
that use this package, such as iSPlot and iSNetwork. Note that the clickEvent
method will also be defined for the spreadView class and this will correspond
to a user selecting a row on the spreadsheet.
