TrajectoryPoint

One sample: its time and the value of every per-sample field at that time.

Full docstring

`header` is the trajectory's: `t` counts from its stamp, and its frame and meta say what the
values are relative to. WHY a point carries it (ROS's points don't): a point taken out with
`traj[i]` or `traj.at(t)` would otherwise lose its frame, origin and units.

Import
