Release Name: R0.8.1

Notes:
=== 0.8.1 / 2010-10-02

* This is the public release of R0.8.0, with additional bug-fixes.
  Note that R0.8.0 will not be released separately as a publicly
  available Rubygem. All changes as listed for R0.8.0 are available in
  this release.

* The main change in R0.8.0/R0.8.1 is conversion of all CamelCase
  method names to snake_case.  The old CamelCase method names will
  still work (to ensure backwards compatibility), but will also
  display a warning.

* The TreeNode#add method now accepts an optional child insertion
  point.

* The subtree from the current node can now be cloned in its entirety
  using the `TreeNode#detached_subtree_copy' method.

* A major bug-fix for bug #28613 which impacted the Binarytree
  implementation.  See
  http://rubyforge.org/tracker/index.php?func=detail&aid=28613&group_id=1215&atid=4793
  for details.
