eval bug

[Jason Ren]

Shouldn't accuracy= TPs / (TPs+FPs)? What computed in below two lines seem to be recall.

splatnet/splatnet/semseg3d/eval_seg.py

Line 38 in f821913

 scores['class_accuracy'] = [TPs[i] / (TPs[i] + FNs[i]) for i in range(len(labels))] 

splatnet/splatnet/utils.py

Line 149 in f821913

 class_acc = [(tp[i] + eps) / (tp[i] + fn[i] + eps) for i in range(len(labels))]

This is how "per-class" accuracy is typically defined for this dataset. It can be considered as "accuracy among points belonging class i"
