// make the menus and provide information on usage
//====================================================================================
//
// In order to customise your menus all you need to do is:
// - edit the styles .dot, .dotoff and .caption
// - add the main menu using the following code
// var [menu_name] = new menuObject("[menu_name]", [x position], [y position], [caption], [spacing between sub menus]);
// - add the subemus using:
// var [sub_menu] = [menu_name].addItem([caption],[action],[spacing]);
// OR
// var [sub-sub_menu] = [sub_menu].addItem([caption],[action],[spacing]);
// OR
// [menu_name].subMenus[x].addItem([caption],[action],[spacing]);
//
// - where action is string that get's evaluated when the dot is clicked
//
// (NOTE the spacing is optional and if left blank gets inherited
// and is equal to the (parent's value)/2 - the default for
// the main menu item uis 400)
//
// - the following allow extra manipulation of the menus:
// + menuItem.show() - show's the menu's dot
// + menuItem.showCaption() - show's the menu's caption
// + menuItem.hide()
// + menuItem.hideCaption()
// + menuItem.startAngle = x - default is 0-degrees which means the first submenu appears
// directly to the right, the following items are traced in a
// clockwise direction
// + menuItem.setCaption("text") - allows you to change a menus caption
// + menuItem.expand() - opens a menus submenus (if they exist)
// + menuItem.collapse() - closes a menu's subItems (unless one of them is open)
//
// + menuItem.moveMe(x,y) - moves a menu to coordinates (x,y)
// + menuItem.moveBy(x,y) - moves a menu by (x,y)-pixels
// + menuItem.x() & menuItem.y() - retrieve a menus coordinates
//
