Correct box plots vs. 0.5-style

```
I'll just state an opinion here and we'll see what happens.

I liked the Jesse-style box plots better. :-)

I don't really care to see outliers pinpointed. Especially since now I like to
run many trials of many measurements, I'm being overwhelmed by black dots.

The old graphs showed me five pieces of information: namely, all five
quartiles. That was perfect, to me!
