// Description:
// =========================
// BROWSER DETECTION VERSION
// br - detailed browser description object
// br.name - browser title: Internet Explorer, Netscape Navigator or Opera
// br.shortName - short name for browser:
//    EXP - Internet Explorer
//    NAV - Netscape Navigator
//    OPR - Opera  
// br.version - browser version
// br.minorVer - minor version (ex: IE4.01 minor is 1)
// br.language - browser lnguage
// br.plainAgentStr - same as navigator.userAgent 
// br.plainNameStr - same as navigator.appName 
// br.plainVersionStr - same as navigator.appVersion 
// IE - true if any version of Internet Explorer
// NN - true if any version of Netscape Navigtor
// OP - true if any version of Opera
//
// =========================
// CROSS BROWSER WINDOW PARMETERS
// Remember to call initDetect() after page loading (in onLoad event) in order
// to use this methods and objects
// client - detailed browser window parameters object
// client.width - width of visible area
// client.height - height of visible area
// client.XOffset() - current offset of left window border
// client.YOffset() - current offset of top window border

// =========================
// CROSS BROWSER POSITIONING & STYLE SECTION
// getX - gets X coordinate in pixels;
// getY - gets Y coordinate in pixels;
// getWidth - gets width in pixels;
// getHeight - gets height in pixels;
// setX - set X coordinate in pixels;
// setY - set Y coordinate in pixels;
// moveTo - moves object to specified x and y coordinates;
// moveBy - moves object by dX and dY distance;
// show - show hidden element;
// hide - hide visible element;
