if you use includeGlobal = 1 then keywords and the description you 
entered in the constants will be listed IN ADDITION to the metatags you 
entered for each page.
if you use includeGlobal = 0 then only the keywords and the description 
you entered for each pages will be listed. the ones in the constants 
will be kicked.
