Missing 2Wcontrol file

[rkulkarni1999]

Hi.. ive been working on differential_drive and was trying to implement hardware interface and then came across your package and wrote a hw_interface by customizing to our robot requirements and in the launch file I've seen there is driver_control package with 2Wcontrol node missing in the current repository could you just give me a peek at it so that I could complete my hardware_interface module.. thanks in advance..!
