Script create_movie.py fails when run on logs associated with study_static_obstacles

[alexperez33]

The executable study_static_obstacles generates a log (info_about_bm.txt) which only contains x,y,z, and r related data about obstacles. The script create_movie.py expects x,y,z,r,vx,vy,vz, so it fails to unpack the obstacle information in info_about_bm.txt generated from study_static_obstacles.

It seems a solution would be to log 0,0,0 as well for each obstacle when logging info_about_bm.txt. This would represent vx, vy, and vz, and allow create_movie.py to function properly.
