plotants produces a plot of the antenna positions taken from the ANTENNA sub-table of a measurement set.  The antennas are plotted Y vs. X in meters, where Y is toward local north and X is toward local east.  This plot can be exported to a figfile in various formats:  emf, eps, pdf, png, ps, raw, rgba, svg, and svgz.

In the plotter window, the user has the option to mark a region then locate, flag, or unflag points in the region.  The user can also zoom and pan the plot, save the plot in png format, or quit.  When hovering the mouse over the plot, the x- and y-coordinates are displayed in the lower right corner.
