social anchors

[NoahWangc]

I write this issue to thank your contributes for trajNet++ which have created a greatly benchmark for trajctory prediction，it helps me to quickly study some core knowledge.

in addition, 《Interpretable Social Anchors for Human Trajectory Forecasting in Crowds》 is a great job, but I have some confusion. I want to study some related codes. Could you please give me the codes? Thank you very much！
