 Revised 17 May 99 to add is_nav5up and is_ie5up (see below).
 Revised 20 Dec 00 to add is_gecko and change is_nav5up to is_nav6up
                      also added support for IE5.5 Opera4&5 HotJava3 AOLTV
 Revised 22 Feb 01 to correct Javascript Detection for IE 5.x, Opera 4, 
                      correct Opera 5 detection
                      add support for winME and win2k
                      synch with browser-type-oo.js
 Revised 26 Mar 01 to correct Opera detection
 Revised 02 Oct 01 to add IE6 detection
 Everything you always wanted to know about your JavaScript client
 but were afraid to ask. Creates "is_" variables indicating:
 (1) browser vendor:
     is_nav, is_ie, is_opera, is_hotjava, is_webtv, is_TVNavigator, is_AOLTV
 (2) browser version number:
     is_major (integer indicating major version number: 2, 3, 4 ...)
     is_minor (float   indicating full  version number: 2.02, 3.01, 4.04 ...)
 (3) browser vendor AND major version number
     is_nav2, is_nav3, is_nav4, is_nav4up, is_nav6, is_nav6up, is_gecko, is_ie3,
     is_ie4, is_ie4up, is_ie5, is_ie5up, is_ie5_5, is_ie5_5up, is_ie6, is_ie6up, is_hotjava3, is_hotjava3up,
     is_opera2, is_opera3, is_opera4, is_opera5, is_opera5up
 (4) JavaScript version number:
     is_js (float indicating full JavaScript version number: 1, 1.1, 1.2 ...)
 (5) OS platform and version:
     is_win, is_win16, is_win32, is_win31, is_win95, is_winnt, is_win98, is_winme, is_win2k
     is_os2
     is_mac, is_mac68k, is_macppc
     is_unix
     is_sun, is_sun4, is_sun5, is_suni86
     is_irix, is_irix5, is_irix6
     is_hpux, is_hpux9, is_hpux10
     is_aix, is_aix1, is_aix2, is_aix3, is_aix4
     is_linux, is_sco, is_unixware, is_mpras, is_reliant
     is_dec, is_sinix, is_freebsd, is_bsd
     is_vms
 See http:www.it97.de/JavaScript/JS_tutorial/bstat/navobj.html and
 http:www.it97.de/JavaScript/JS_tutorial/bstat/Browseraol.html
 for detailed lists of userAgent strings.
 Note: you don't want your Nav4 or IE4 code to "turn off" or
 stop working when new versions of browsers are released, so
 in conditional code forks, use is_ie5up ("IE 5.0 or greater") 
 is_opera5up ("Opera 5.0 or greater") instead of is_ie5 or is_opera5
 to check version in code which you want to work on future
 versions.

     *** BROWSER VERSION ***
     Note: On IE5, these return 4, so use is_ie5up to detect IE5.  */
