     * Replace characters having special meaning inside HTML tags
     * with their escaped equivalents, using character entities such as '&'.
     *
     * The escaped characters are :
     *  < > " ' \ &
     *
     * This method ensures that arbitrary text appearing inside a tag does not "confuse"
     * the tag. For example, HREF='Blah.do?Page=1&Sort=ASC'
     * does not comply with strict HTML because of the ampersand, and should be changed to
     * HREF='Blah.do?Page=1&amp;Sort=ASC'.
     * This method always returns a new String
     * @param text input text to be escaped
     * @return result the escaped text
