// TTable3Points class is to create 3D view of any 3 columns of the TTable objects
// with one and the same "key column value".
//
// For example all values of the column "x[0]" "x[1]" "x[2]" of the g2t_tpc_hit table
// from the rows with one and same "track_id" column value will be regarded
// as an image of one and the same "track".
// The last means all those points will be painted with one and the same 3D
// attributes like "color", "size", "style", "light","markers", "connections" etc.
//
// The original TTable object must be pre-sorted by "key column" via TTableSorter
// class
//
// void CreatePoints(Tg2t_tpc_hit *points)
// {
// g2t_tpc_hit_st *p = points->GetTable();
//
// TTable3Points *track = 0;
// TString tr;
// tr = "track_p";
// TTable &ttt = *((TTable *)points);
// // Track2Line MUST be on heap otherwise 3D view will crash just code leaves this
// // subroutine
// We will assemble all points by its "track_p" field.
//
