Haptic App check for devices

[geraldb]

haptic app should NOT throw an error if no haptic device is discovered AND no haptic device is actuall requested

int tmp_n_haptics_connected = haptics_.connectToDevices();
if(0 >= tmp_n_haptics_connected)
{ throw(std::runtime_error("Could not get connect to haptic devices"));  }

Then why use haptic app anyway? You can change the behavior in your own app. I think that the standard is better this way.
