Higher API for training

6

## 🚀 Feature Higher API for training will improve usability of Ignite as Keras did. My implementation [here](https://github.com/Minyus/pipelinex/blob/master/src/pipelinex/ops/ignite_ops.py) could be used as the base code.

Add mAP metric for object detection

3

It would be a good idea to add a mAP metric which is often used in object detection. For this the newly added [IoU](https://github.com/pytorch/vision/blob/master/torchvision/ops/boxes.py#L102-L124) function from torchvision could be used.
