UBUNTU distributable version of ACTIVE hub software

a distributable version of the "hub" software. The scope of "hub" software is to route all the data coming from every component of the ACTIVE Project (KUKA LWR robots, Active Headframe, Sigma haptic devices, On-Field cameras, software modules creating virtual constraints ...). As consequence, a distributable version of this software allows every project partner in testing its component connection with other parts of the system. This distributable software has been developed under non real-time enviroment (linux-Ubuntu).
