Minimal code for reading pointclouds in bag file and visualizing them with Open3D

[evbernardes]

I'm starting to work with a Realsense camera and I'd like to use Open3D to do some processing of pointclouds.

I didn't manage to find any examples that do the following:

1. Open bag file with recorded video from Realsense
2. Transform depth_images into pointclouds
3. (Optional) do something with pointclouds
4. Show pointclouds on a visualization window
5. Repeat for next frame until the end

Can someone share a minimal code that does this?
