NAME
       catchmark - iostream manipulator

DESCRIPTION
       The catchmark is used for building labels used for input-output of vector-valued fields (see field(2)):

	       cin  >> catchmark("f")	>> fh;
	       cout << catchmark("u")	<< uh
		    << catchmark("w")	<< wh
		    << catchmark("psi") << psih;

       Assuming its value for output is "u", the corresponding labels will be "#u0", "#u1", "#u2", ...

IMPLEMENTATION
       class catchmark {
	   public:
	       catchmark(const std::string& x);
	       const std::string& mark() const { return _mark; }
	       friend std::istream& operator >> (std::istream& is, const catchmark& m);
	       friend std::ostream& operator << (std::ostream& os, const catchmark& m);
	   protected:
	       std::string _mark;
       };
