Font family and style cannot be customized

[kingcrimsontianyu]

Dear dev,
It appears that the code below invoked before plot.nn() would have no effect on the font family and style, and the only customizable parameter is fontsize that must be set via plot.nn(). Is this by design, or am I missing anything? Thank you.

    par(
        family = "Consolas",
        font = 2,      # 2 refers to bold face, for text
        font.lab = 2,  # for x-y labels
        font.main = 2, # for main titles
        font.sub = 2,  # for subtitles
        font.axis = 2
    )

You can use grid::gpar() arguments, e.g.:

plot(nn, rep = 1, fontface = "italic", fontfamily = "sans")
plot(nn, rep = 1, fontface = "bold", fontfamily = "mono")

Unfortunately, these are used for all text in the plot (via ... argument) and I don't see an easy way to change that.

As noted in #31, the plot function is not easy to customize and definitely needs some refactoring.
