Plotting: reference angles still in radians ??

[fabfabBesnard]

Problem: the div. angles values of the reference sequence are completely aberrant
I suspect the angles are just in radians.

e.g.
dataset: 2018-11-27_15-13-03
(see on amazon server: ~/database_fabfab/test_pipe/v010_dbeval1_geom/2018-11-27_15-13-03
run with docker image: roboticsmicrofarms/plant-3d-vision:latest
command: romi_run_task AnglesAndInternodesEvaluation --config /myapp/configs/geom_pipe_real_v010_dbeval1.toml /myapp/db/2018-11-27_15-13-03
