IVU control window

IVU Control Window.

Nice @RafaelLyra8 ! Maybe we could change the tag "Change Kparam" to "Start Movement", once the same button starts pitch and center movements.
Also, I think we can add the following protection systems in this window:

• When you try to disable center mode or pitch mode with a center offset or pitch offset different from zero, the undulator automatically sets these PVs setpoints to zero and moves the undulator; only then are the pitch mode or center mode disabled.
• When you try to change the Kparam with pitch mode and center mode enabled, a message telling the user to disable these modes appears on the screen.
  I think it would be great to have this protection system by now, once our movement tests showed that the undulator control system is not robust when combining different movements. After the upgrades in the PLC code, we can remove these protections.

What do you think, @fernandohds564 , @xresende, @RafaelLyra8 ?

I don't know if I understood correctly @Gabrielrezende-asc. Can we talk offline in person?

another option is for the window just to complain that the requirements are not met, instead of acting on the IVU on behalf of the user. The window could have a warnning pop-up suggesting how to proceed, instead of acting. I think this is safer behaviour.
