Base framework for a touchscreen emergency stop button. No funtionality yet.
First working version. Should stop motors on button press. Still not clean. Segfaults when closed because ros::spin is not properly terminated yet.
Toggle between emergency stop and reset motors.
bug fix.
Button now changes colour when pressed and motors are successfully stopped.
Making Qt stop gracefully when catching sigint or sigterm.
Calling ros::shutdown when Qt app quits.
Listening to the /bumper topic to determine the real state of the motors instead of guessing from service success.
Button toggle is now based on service success.
Fixed dependencies and removed "glob"-ing from CMakeLists to make it clean.
added scitos_msgs_genccp dependency.
Added documentation.

Remodeling the emergency stop button into an rqt plugin.
First attempt. Limited functionality.
Missing connect function added to give some functionality to the button.
Complete restructuring.
Getting rid of ros_comm because it is not needed and complicates erverything.
Bug fixing:
forgot to start the ros:spin thread and had to add a ! for the colour change

The button is now a bit smaller to be able to use something else besides the button in rqt.
The colour is now only changed if there is real change in the value.
Added some comments and deleted rubbish from package.xml
start with assumption that motors are off in the beginning.
