UI

[ihkao]

Close #40
In order to test the UI, run the following command:
ros2 run fabric_gui fabric_gui_exe

There are stiil some works to do:
Ploting figure to show histogram and lines of each topics.
Design an UI format for building custom yamls.

To avoid too many lines of code review, I prefer to merge this workable version first.

Tested working. However, sometimes I couldn't pause after launching, like the screenshot above.

The screenshot suggests that you've paused and obtained the measurement result.
You can only activate the pause button after pressing the launch button.
There's a logic in place ensuring that the launch and pause buttons aren't both enabled simultaneously.

@ihkao Maybe this one? The pause is greyed out right after I hit launch. This happens when I switch rmw.

I've merged as of now. As last time we discussed, the above issue only exists because once we find an available dds, the launch button won't be greyed out for other unavailable dds even if we switch later.
