Yaohua Xiong 5241464a46 Refactor Curv3D and PathFollow3D ...

This commit makes the following major changes

1. Add "sample_baked_with_rotation()" to Curve3D, making it usable independently. A similar change was made to Curve2D previously.
2. Refactor the _bake() method on Curve3D, using Parallel Transport Frame instead of Frenet Frame.
3. Refactor the sample_* methods, including:
  i. Factor out common binary search code, following the DRY principe
  ii. sample_up_vector() interpolated up vector as part of rotation frame(posture) for consistancy and accuracy.
