Changes in v2.11
    * Added hdrbw() from Matt Wand to compute better bandwidths for hdr(), hdr.den() and hdr.boxplot().
    * Fixed a few bugs in the help files.

Changes in v2.10

    * Bug fix in hdr.boxplot.2d(). The show.points option was not working.

Changes in v2.09

    * Bug fix: the a bandwidth in cde() when fw=TRUE and use.locfit=TRUE was twice as large as it should have been.

Changes in v2.08

    * Bug fix in hdr.boxplot.2d(). It would sometimes plot outliers on a separate plot.
    * New argument to hdr.boxplot.2d() to allow the density to be estimated using the kde() function from the ks package.
