Follow up work of #41 about open3d HOT 4 CLOSED

We should also show case a complete tutorial starting from downloading one of the TUM sequences, then ran odometry, then evaluating. In general, what we did in our paper.

from open3d.

We have better OpenMP support from the discussion of #52, but when the enhanced OpenMP code applied to RGBDOdometryJacobian, the performance gain is still not as drastic as #52. I think maybe due to extensive random correspondence search and memory reference.
One way to boost is reducing the number of correspondences: not searching correspondences for every pixels, maybe for every two pixels. This will boost 4x at least.

Fixed. See #52 and #53.

Offline discussed, but making tutorial has higher priority for now.

Done. Close.
