   If the receiver object, this, is an infinite sequence 
   this method will not terminate if there is no match.  Similarly, if 
   the both the receiver object and the argument, that are 
   infinite sequences this method will not terminate.
  
   Because both the receiver object and the argument can both potentially 
   be an infinite sequences, we do not attempt to use an optimized 
   searching algorithm.  Therefore, the running time will be proportional
   to the length of the receiver object and the argument.  Subclasses and 
   traits can potentially provide an optimized implementation.
      
        Returns
-1 if that not contained in this,    otherwise the smallest index where that is found.
