the variable names of qrs, pts are so misleading!

[cam1681]

In the paper, the authors use q to denote query points and p to denote representation points. But in the code, qrs is used to represent representation points and pts for query points. The mess makes the code very hard for comprehension for a newer like me. Hope you can change the names or give some notation in README at least. Thanks, on the behalf of the possible dazed people. I worked it out for a whole day.....
