Fixes #22

Deregister the signal formerly added.
Add a mutex system to prevent removing a signal while triggering it,
 to avoid a crash (especially if the topic was listened to).

Update CMakeLists.txt to install libros_bridge

this will allow to close Issue #18

  It seems that everybody is still using the old style ROS build system...

  Previous commit was not on official repository.

  Fix distcheck target.

  Without this call the command fails.

Conflicts:
	CMakeLists.txt

Modify RosRobotModel to derive from sot::Dynamic

migration to catkin_make 

Fix compilation error "floating-point literal cannot appear in a constant expression".

The old names are kept for now, but will disappear in the
future.

Reimplement runsource to reset the cache in case of SyntaxError

Behaviour of runsource based on:
http://docs.python.org/2/library/code.html

Retry the command (one time only) if the connection was lost

  Launching an application in a roslaunch file may cause to send python
  command before the interpreter has read the prologue. This commit should fix
  this issue.

Setting up ROS:
rosparam load `rospack find hrp2_14_description`/sot/hrp2_14_reduced.yaml
rosrun robot_state_publisher state_publisher

Display the robot using the info given in
https://trac.laas.fr/gepetto/hrp2/hrp2_14_description/html/reference/

To repeat at each simulation:
rosrun dynamic_graph_bridge geometric_simu --input-file ~/devel/ros-unstable-2/install/lib/libsot-hrp2-14-controller.so
rosrun dynamic_graph_bridge run_command
>>> from dynamic_graph.sot.application.velocity.precomputed_tasks import *
>>> solver=initialize(robot)
rosservice call /start_dynamic_graph
>>> Put_whatever_you_want_in_python

The rationale is to use a state vector map provided by the robot stack.
For instance for hrp-2 we have a yaml file providing the ros parameter:
/sot/state_vector_map
which specifies the state vector:
[RLEG_JOINT0, RLEG_JOINT1, RLEG_JOINT2, RLEG_JOINT3, RLEG_JOINT4, RLEG_JOINT5, LLEG_JOINT0,
  LLEG_JOINT1, LLEG_JOINT2, LLEG_JOINT3, LLEG_JOINT4, LLEG_JOINT5, CHEST_JOINT0, CHEST_JOINT1,
  HEAD_JOINT0, HEAD_JOINT1, RARM_JOINT0, RARM_JOINT1, RARM_JOINT2, RARM_JOINT3, RARM_JOINT4,
  RARM_JOINT5, RARM_JOINT6, LARM_JOINT0, LARM_JOINT1, LARM_JOINT2, LARM_JOINT3, LARM_JOINT4,
  LARM_JOINT5, LARM_JOINT6]
