[ros] docstring: on the way to generate doc :+1:
[odometry] set integrated level as default
Add new tutorial on quadrotors.

Inspired by the cat and mouse game.
Use the waypoint actuator for the quadrotor.
Merge branch 'master' of ssh://trac.laas.fr/git/robots/morse
[ros] docstring use ros_class variable

Used to create the topic and to generate doc.
While here, add a default_frame_id for some components, the one without
will keep the morse convention, which is the same than the topic name
("/robot/sensor"). Which can also be overriden by an kwargs of name
"frame_id".
[ros] pseudo-wrap mathutils for docgen
[doc] add tool to generate datastream doc
[pr2] Updates to PR2 blender model

- Adjusted torso armature to have correct '0'
- Reparented torso_lift children to torso_armature

This would previously prevent the head and arms to move along with the torso.
It actually looks like a bug in the BGE (or at least, an inconsistency).

This change also required clearing the parent inverse matrix of head and arms, and
updating accordingly transformations of these parts. This have introduce small
inaccuracies in bodies placement compared to original URDF.
[armatures] Fix misplaced 'armature.update'

This would prevent prismatic joints to actually move
[armatures] Correctly read prismatic joint value + minor refactoring

We assume the joint elongation is always on Y (ie, channel.pose_head[1]). Need to be checked
with other prismatic joints, though.

Unit-test robots/pr2/torso-sockets.py now pass.
[examples] delete outdated armature_samples

and references in doc
[examples] update rosace example
[examples] deleted outdated pr2/hri scenarii
[builder] pr2: do not super(self.__class__, self)
[profile] add block /10
[human] default classpath
[examples] update ros example multi

``del env`` to create MORSE configuration.
[builder] Provide add_overlay and add_modifier

No expected changes, but consistency of builder API.
Depreciate configure_overlay and configure_modifier
[testing] Adapt odometry test to match semantic changes

0eb98a8 moves v and w from differential to integrated and
9ad926 changes the default level to integrated.

However, the test is still broken :D
[sensor/odometry] Fix commit 0eb98a8

0eb98a8 moves the definition from vx, vy, vz ... from differential to
integrated, but does not move the real computation. Fix it :).
