/** The InitialCompanyNameListener class has static
 *  methods that permit access to the current and former
 *  company names. But, using these methods in JSP requires
 *  explicit Java code, and creating beans that provided
 *  the information would have yielded a cumbersome result.
 *  So, we simply move the code into a custom tag.
