An argument of 4 to BOX stops that axis from being drawn. The algorithm for choosing axis labels now checks that there is enough room for the labels that is has chosen and acts accordingly.
Searches are now by default case in-sensitive.
Added atof to convert string-valued vectors to arithmetic. The devices tpic and gpic can be used to generate figures that TeX can pass to dvips and xdvi. Axis ticks are also suitable scaled.
