* This code is licensed LGPLv3
*
* This code is a Java port of the original work in PHP by Cal Hendersen.
* http://code.iamcal.com/php/lib_filter/
*
* The trickiest part of the translation was handling the differences in regex handling
* between PHP and Java. These resources were helpful in the process:

* http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

* http://www.regular-expressions.info/modifiers.html
*
* A note on naming conventions: instance variables are prefixed with a "v"; global
* constants are in all caps.
*
* Sample use:
* String input = ...
* String clean = new HTMLFilter().filter( input );
*
* The class is not thread safe. Create a new instance if in doubt.
