// rgi[] is an array of pointers into rgP
//
// rgP[] must have at least the following entries for menus
//		.link .............. page to goto when clicked
//		.iPage ............. menu identifier (handle) associated with each link page
//		.wMenu ............. width of the <TD> for a menu item
//		.display ........... text to be displayed if (fImages == false)
//		.img ............... image to be displayed if (fImages == true)
//		.img_hl ............ mouseOver version of image
//
// plus the following for sub menus
//		.iMenu ............. identifier to distinguish menu class names
//		.xOffsetSubMenu .... how far [y] from the top left of the <TD> or <IMG> of menu item to show sub menu
//		.yOffsetSubMenu .... how far below the bottom of the <TD> or <IMG> of menu item to show sub menu
//		.wSubMenu .......... width of sub menu in pixels
//		.subMenuDiv ........ ID of <DIV> enclosing subMenu for this menu item
//		.rgSubMenu[] .. 
//		.nrgSubMenu ... 
//
// rgSubMenu[] must have following entries
//		.link .............. page to goto when clicked
//		.display ........... text to be displayed if (fImages == false)
//		.img ............... image to be displayed if (fImages == true)
//		.img_hl ............ mouseOver version of image
//
