// getBrowserInfo - Generate an object to hold browser info.
//
//  Overview:
//	getBrowserInfo creates an object named brInfo which contains:
//	  brInfo.brver - (int) browser version: version number of browser 
//	  brInfo.isie - (boolean) browser is MS Internet Explorer
//	  brInfo.isns - (boolean) browser is Netscape Navigator
//	  brInfo.ieok - (boolean) browser is ie version okver or greater
//	  brInfo.nsok - (boolean) browser is ns version okver or greater
//	  brInfo.okver - (int) the okver that the brInfo object was built with
//	  brInfo.iswin - (boolean) platform is MS Windows
//	  brInfo.ismac - (boolean) platform is Mac
//	  brInfo.range - (string) DOM range: "" if netscape "all." if IE
//	  brInfo.style - (string) DOM style: "" if netscape ".style" if IE
//	    [Note this can be used to construct the object reference e.g.:
//	     'document.' + brInfo.range + objectName + brInfo.style]
//
//  Input parameters:
//	okver - (optional) The minimum accepted browser version used to set
//		brInfo.ieok or brInfo.nsok to true
//		The default value of okver is 4
//
//  Return value:
//	none
//
//  Notes:
//	Since brInfo is global, it may be changed by sequential getBrowserInfo calls.
//	Therefore, you may want to check brInfo.okver to make sure the acceptable browser
//	 version is what you think it is from one brInfo reference to the next.
