   It is claimed that a topology O on a space M is the simplest structure   
   which affords a notion of continuity. Two questions:   
      
   1] is there a proof of this?   
      
   2] what other structures on spaces (considered as sets of points) give   
   notions of continuity?   
      
      
   Thanks
