Add Object Detection notebook(s)

[ryanloney]

Placeholder for Object Detection notebook with OMZ models.

We may need to rethink this and show how to convert models for object detection, and not just download from OMZ. There are a few public models in OMZ that we could show how to convert with Model Optimizer. One idea is making a 20X-object-detection directory with 20X-object-detection-yolv3.ipynb and 20X-object-detection-xyz_model.ipynb.
