I made a prototype wrapper for the ROOT gui system that handles layout based on a configuration (json) file. Added half a GUI as part of the set up process.

Probably got 12 good hours working on this during the CM.

Another 16 hours or so - have a functional prototype that makes some plots. Have dialogues for selecting beam and for manipulating magnet currents, plus an embedded canvas that holds plots of propagated beam envelope variables. Working on the plotting dialogue, and haven't started any tests or documentation at all...

Still to do then:

• Plotting dialogue (8 hours) 6 hours
• Backend mod - field element aperture (8 hours) 4 hours
• Backend mod - propagate reference particle (for mean energy etc) (8 hours) 4 hours
• Tests of the ROOT GUI wrapper stuff (8 hours) 4 hours
• Tests of the actual logic (8 hours) 8 hours
• Document, pylint and prettification (8 hours) 2 hours
  • (pylint was done with everything else)

So looks like I will overrun the 56 hour estimate for effort required by ~ 30 %. Let's wait and see.

Additionally:

• Reasonable geometry set up
• Bug fix - ROOT TGTextEntry is throwin segv if I update it by hand (not if I update it automatically)
• Exception handler (5 hours)

I think that this is reasonably complete now.

The outstanding issue is a reasonable geometry description. I think this is predicated on Ryan finishing what he is up to, so I won't press it now.
