/**
 * A simple, static class to display a URL in the system browser.
 * 
 * 
 * Under Unix, the system browser is hard-coded to be 'netscape'. Netscape must be in your PATH for this to work. This
 * has been tested with the following platforms: AIX, HP-UX and Solaris.
 * 
 * 
 * 
 * Under Windows, this will bring up the default browser under windows, usually either Netscape or Microsoft IE. The
 * default browser is determined by the OS. This has been tested under Windows 95/98/NT.
 * 
 * 
 * 
 * Examples:
 * 
 * 
 * 
 * BrowserControl.displayURL("http://www.javaworld.com")
 * 
 * BrowserControl.displayURL("file://c:\\docs\\index.html")
 * 
 * BrowserContorl.displayURL("file:///user/joe/index.html");
 * 
 * 
 * Note - you must include the url type -- either "http://" or "file://".
