011 /**
012 * An extensible stylesheet that enforces a default look-and-feel for all
013 * EchoPoint Google Chart API components. Can be used as the starting point
014 * for applications built using the framework. We hope this promotes an
015 * object-oriented management of styles for applications.
016 *
017 * <p>It is recommended that you extend from {@link echopoint.Servlet} (in
018 * the webcontainer area) since the base servlet takes care of initialising
019 * default style properties from init parameters.</p>
020 *
021 * <p>This class is based upon the
022 * <a href='http://sptci.com/docs/public/com/sptci/echo/style/StyleSheet.html'>StyleSheet</a>
023 * implementation that <a href='http://sptci.com/'>SPT</a> has used as the
024 * basis for building a number of Echo2/3 applications.</p>
