Install the package +floatingBaseBalancingTorqueControlWithSimulator

- minor hack: in the main CMakeLists.txt of the whole-body-controllers, the script returns to the caller before running 'add_subdirectory(controllers)'. As a result, the respective CMakeLists.txt doesn't run, so we had to add the copy commands directly to the main CMakeLists.txt.

+For running the simulation from the source module (for developpers wishing to perform any modification), follow the few steps below:
 1. Set the `YARP_ROBOT_NAME` environment variable to the desired model. The default and only currently supported model is `iCubGazeboV2_5`. There is no direct link with Gazebo. This model is suitable for the `matlab-whole-body-simulator` because of the modified inertia of the intermediate small and light links within the 3-DoF joints (shoulder pitch-roll-yaw, hip pitch-roll-yaw, etc), tuned for stabilising the dynamics of the simulation.

 ### Configuration file
 
 At start, the module calls the initialization file `initTorqueControlBalancingWithSimu.m`. Once opened, this file contains some configuration variables. Please follow the instruction inside the script to properly configure your simulation.
