code: public static <T> boolean containsNull(T...hayStack)
  	{
  		if(hayStack == null)
  			return false;
  		for(T hay : hayStack)
  			if(hay == null)
  				return true;
  		return false;
  	}
docs: Does an array contain a null value?
  @param hayStack the array to look in
  @return true if hayStack was non-null and contained a null value. false otherwise
