-	*
-	*	This version is a bit of a rewrite to match my own coding style and use some of the
-	*	capabilities allowed in PHP5.  Since this was a significant rewrite, but it still
-	*	maintains backward compatibility syntax-wise, the version number is now 1.0.0.  Any
-	*	minor changes that do not break compatibility will be indicated in the second or third
-	*	digits.  Anything that breaks compatibility will change the major version number.
-	*
-	*	PHP5 specific changes:
-	*	+ Private methods are now in place
-	*	+ __construct() is now used rather then the standard class name 'kses()'
-	*	+ Kses will not load in any version less that PHP5
-	*	Other modifications:
-	*	+ PHPdoc style documentation has been added to the class.  See http://www.phpdoc.org/ for more info.
-	*	+ Method names have been changed to reflect status as verbs
-	*	+ One line methods have been folded into the code
-	*	+ Some methods are now deprecated due to nomenclature style change.  See method documentation for specifics.
-	*	+ Kses5 now works in E_STRICT
-	*	+ Version number is 1.0.0 to reflect serious code changes
-	*	+ Addition of methods AddProtocols(), filterKsestextHook(), RemoveProtocol(), RemoveProtocols() and SetProtocols()
