Support titles using main argument in plot.euler.

Unfortunately the title doesn't show up in the plot. I also tried par(oma = c(0, 0, 5, 0)) to no avail.

What is strange is that last time I did this (about a year ago) it worked alright.

eulerr changed to an internal solution for plotting the diagram in a recent release. It used to rely on lattice, which supported adding a title. You can currently add a title by hand using, for instance, gridExtra::grid.arrange() and grid::textGrob().

Could you provide a small code example how to create a diagram with title? Thank you

I also tried title but it gave me an error too: "Error in title(main) : plot.new has not been called yet" This is really inconvenient.

Just some context: I am writing a book about R and I wanted to use your package as the main package in one chapter... but this is really troublesome. Just out of curiosity: why did you change the plotting engine? It seemed to work better than the solution now. Could I use the development version from github or does it have the same problems?

Ok so the following works:

fit1 <- euler(c("A" = A, "B" = B, "C" = C, "A&B" = AnB, "A&C" = A, "B&C" = B, "A&B&C" = AnB), input = "union")
plot1 <- plot(fit1, fill = c("red", "green", "gray90"))
grid.arrange(grobs = list(plot1), top = "test")

Thanks, @vonjd, I had tried several options as well. Also feel a short example like this in the docs would be very helpful.
