Expose the vehicle heading

This is last value in https://pixhawk.ethz.ch/mavlink/#GLOBAL_POSITION_INT

I think we can infer it from the Vehicle.velocity, but often people just want general direction.

We'd need to make sure no one would confuse it for direction the vehicle is facing. Can we make velocity a Vector3 object and then have a Vector3.direction function?

Agreed. I think that is a documentation issue.

I don't know anything about Vector3 and the costs/benefits of changing it from a list. My thought is that this would be useful if we needed to perform vector operations - and I imagine we will?

@mrpollo When you have time, would be good to have your feedback on this proposed change.

We currently expose the VFR_HUD property heading as vehicle.heading. Is this issue resolved?

[hamishwillee]

@tcr3dr Since when? I never saw or documented this! Any other new ones you've added recently? I can see sys_status too, but I don't think anything else?

Yes this can be closed, but can you add a new issue to document it, and any other new attributes you added recently?

[hamishwillee]

@tcr3dr So the changelist above adds docs for system status and heading. If there are any other new attributes (other than isarmable) let me know :-)

If not, IMO this can be set resolved.

@hamishwillee .heading snuck in during the Solo feature merge I think, heh. It is the only attribute I know of to get that treatment.

Great. We got an early request for this some time ago, so I'm sure our users will be very happy.
