I do it myself using the Standart Template library. You can use the
"set" container or call "unique" explicitely. You would need to define <
operator, I do it e.g.


  class Triangle{//class Triangle
  int n1, n2, n3;//nodes
  public:
  //...
	 int id1()const{
		assert(n1 != n2 && n2 != n3 && n3 != n1);
		return min(min(n1, n2), n3);
	 }
	 int id2()const{
		assert(n1 != n2 && n2 != n3 && n3 != n1);
		if(n1>id1() && n1<id3())
		  return n1;
		else if(n2>id1() && n2<id3())
		  return n2;
		else if(n3>id1() && n3<id3())
		  return n3;
		else assert(0);
		return -1;
	 }
	 int id3()const{
		assert(n1 != n2 && n2 != n3 && n3 != n1);
		return max(max(n1, n2), n3);
	 }

	 bool operator < (const Triangle& rhs)const{
		if( id1() != rhs.id1() )
		  return( id1()<rhs.id1() );
		else if( id2() != rhs.id2() )
		  return( id2()<rhs.id2() );
		else return id3()<rhs.id3();
	 };


and then all STL goodies are there for you.

It would also be great if the utility checked for degenerate cells (ones using the same vertex more than once) and for duplicate vertices (ones closer than some tolerance).
