Title: Add boxplot

This patch adds a box plot (or box and whisker plot) to pygal. For each series, it will render a box bounded with the first and third quartiles of the supplied values and with a line bisecting the line at the median. Whiskers are plotted at a distance of 1.5 times the interquartile range (q3 - q1).
