[onebook-core] Graphs and stuff

[Andrew S. <And...@Co...>]

I think it'd actually be pretty cool to put a short statement in abut
what the statistics gleaned from sourceforge are really good for.  For
example, though midway through the semester it shows me as having 10000
lines of code added, that isn't accurate, because although 1/3 was
javadoc and stuff, about 2/3 of that was header code.  So my graph is
skewed funny because of the weight of that one week, so contributions of
a few hundred lines get easily lost in the bottom of the graph.

I'm just thinking it may be helpful to point out issues like this when
you link to the statistics, so it seems they're more adequately
introduced.

I think we're all in agreement that they're definitely useful, if
understood in the correct context.
