/* Class to handle a D_CODE when plotting a board using Standard Aperture Templates
 * (complex apertures need aperture macros to be flashed)
 * 5 types:
 * Circle (round)
 * Rectangle
 * Obround (oval)
 * regular polygon
 *
 * We need round apertures to plot lines, so we also defined a aperture type for plotting
 *
 * Other aperture types are aperture macros
