A container for PlotComponents that conforms to being laid out by
PlotFrames. Serves as the base class for other PlotContainers.
PlotContainers define a layout, i.e., a spatial relationship between
their contained components. (BasePlotContainer doesn't define one,
but its various subclasses do.)
BasePlotContainer is a subclass of Enable Container, so it is possible to
insert Enable-level components into it. However, because Enable
components don't have the correct interfaces to participate in layout,
the visual results will probably be incorrect.
