/** Abstract base class for demo servlets.  Provides a consistent
 *  look&feel for the servlet based demos. Subclasses are only
 *  required to display the portions of the page relevant to their
 *  demo, minimizing the amount of clutter in the demo code.
 *
 * The servlet is based on the template method pattern. Subclasses
 * are required to implement the <code>writeMainBody method.
 * the basic structure of the page is already laid out when this
 * method is invoke so there is no need to for <body> or
 * <head> type tags.
