How to implement on the origin mmdetection

[FibonacciZ]

I've installed mmdetection and I want to implement your algorithm，compared with the original mmdetection, does your implementation only need to add the following files：
1.configs/vfnet
2.models/dense_heads/vfnet_head.py
3.models/detectors/vfnet.py
4.models/detectors/varifocal_loss.py

The answer is roughly Yes, but you also need to register these modules by adding them in corresponding init.py files.

But I think you do not need to implement it by yourself. Please see this pull request.
