Possible error in step() function in Environment file for Quadrotor

[Aakriti05]

The step() function in Environment.hpp file of the quadrotor environment returns the summation of positionReward_ , thrustReward_ and orientationReward_. The coefficient of thrustReward_ is 0, so its value will be 0, and angVelReward_ in not included even though it has been calculated.
So, is angVelReward_ intentionally not included in the summation or is it just a small error?

I haven't really tried to find a nice reward configuration of this task yet. I'll soon update this code to be as close as possible to my original publication.
