Rescue people
   The goal of this exercise is to implement the logic that allows a quadrotor to recognize the faces of lost people and save their locations in order to perform a subsequent rescue maneuver.

First steps:
  The strategy to follow will be: go to the coordinates, make a sweep looking for bodies, if one is found, it descends so it can see the faces and then starts making an spiral.


After trying the program the spiral will be changed fro a smaller sweep.
Then the robot will return to the boat.
As we can see in the video, the drone detects 6 people, keeps looking around and then goes back to the boat.
The coordinates of the bodies are printed on the terminal in a list that updates as the drone finds bodies.
