-  SortTable
-  version 2
-  7th April 2007
-  Stuart Langridge, http://www.kryogenix.org/code/browser/sorttable/
-
-  Instructions:
-  Download this file
-  Add <script src="sorttable.js"></script> to your HTML
-  Add class="sortable" to any table you'd like to make sortable
-  Click on the headers to sort
-
-  Thanks to many, many people for contributions and suggestions.
-  Licenced as X11: http://www.kryogenix.org/code/browser/licence.html
-  This basically means: do what you want with it.
