QueryAndGroup function BUG

[alfredtorres]

Hi,
Thanks for your work on point cloud process.
I find something maybe wrong in your code.
In the QueryAndGroup function, if use raw_grouped_xyz=grouped_xyz, the raw_grouped_xyz and grouped_xyz is actually one vaiable sharing the same pointer.
So when changing the grouped_xyz, the raw_grouped_xyz will also change.

Relation-Shape-CNN/utils/pointnet2_utils.py

Line 388 in cc52c48

raw_grouped_xyz = grouped_xyz

The result new_features just contains related coordinates no absolute coordinates.
I don't sure whether it only occur in my code, please check it.

Thanks for your sharing projcet.
