/**
 * This class can be used at design time to preview the report
 * templates. It was included in the main library as a development tool in order to make up
 * for the missing visual designer.
 * <p>
 * The class is a simple
 * Swing-based Java application that can load and display a report template either in its raw
 * JRXML form or in its compiled form. Even though it is not a complex GUI application and
 * lacks advanced functionality like dragging and dropping visual report elements, it is a
 * very helpful tool. All the supplied JasperReports samples were initially created using this design
 * viewer.
 * </p><p>
 * All the supplied samples already have Ant tasks in their <code>build.xml</code> files that will launch
 * this design viewer to display the report templates.
 * There are two Ant tasks for each sample report: <code>viewDesign</code> and <code>viewDesignXML</code>. The
 * first one loads the compiled report template that is normally found in the <code>*.jasper</code> file.
 * The second one loads the JRXML report template, which is more useful since you can
 * edit the JRXML file and click the Reload button to immediately see the modification on
 * the screen.
 * </p>
