Overview Plot

%OVERVIEWPLOT creates a plot with an interactive overview axes.
% OVERVIEWPLOT(...) takes the same input arguments as the PLOT command
% and will create a new figure containing the plot and an inset
% displaying an overview of the plot. Pan and zoom operations on the main
% axes will result in a rectangle being drawn in the inset axes
% representing the section of the data currently shown in the main axes.
% Manipulating the rectangle has the same effect as panning the main
% axes.
% OVERVIEWPLOT(FIG,...) will put the main axes and inset axes into the
% figure represented by the handle FIG. Any callbacks active in the
% figure will be overwritten as will any data present in the figure.
