0.4.1

Training:

• focus max on 2 people per action with ROI smoothed box. Crops frames to reduce background noise.
• add checkpoints for training
• Training improved: during 25 epoch, training accuracy reaches 0.9 instead 0.4

Action recognition:

• change from raw numbers to softmax. Prevents labels detector (Advanced setting) to go above 100%

Fix:

• In pipeline limit actions, which are consider in grouping to prevent app hang.
