This is updating and adding tutorials to the example project
It solves #85

Thank you. It looks good.

One question is the absolute paths in the config file (for the URDF, in particular) : in works in the docker, but this is still an absolute path... One idea would be to use utheque.hpp to find the URDF. The problem is that this adds a dependency, but on the other hand this is a cleaner approach (and no need to compile robot_dart for utheque only).

What do you think?

[dalinel]

Yes true it would be cleaner to use utheque.hpp
What do you think about adding an option COMPILE_UTHEQUE_EXAMPLES as we did for robot_dart here ?
The dependency would then be optional

[jbmouret]

My idea was to use utheque when we load the urdf in the controller. In that case. We could make it a light dependency with #ifdef : if utheque, is not found, we use the path directly, otherwise we call utheque.

[dalinel]

ok yes this is better and lighter
