Fix KDE example.
It should have been using a probability (density) histogram. I think
there used to be a bug in d3.layout.histogram, which is now fixed.

Add bandwidth selectors for Gaussian kernels.
Thanks @jfirebaugh for the suggestion! Implementation is based on that of R's
stats module:
<http://stat.ethz.ch/R-manual/R-patched/library/stats/html/bandwidth.html>
This brings a few additional operators to `d3.stats`, including a fairly
rudimentary implementation of variance, discussed at
<http://en.wikipedia.org/wiki/Algorithms_for_calculating_variance#Two-pass_algorithm>.

Add kernel density estimation.
Kernel density estimation is provided via `d3.stats.kde` and the kernel is
configurable; several common kernels are provided in `d3.stats.kernel`.
