Deleted some vestigial comments.
Progress towards storing a history so that parameters can be adjusted between calls to solve.
Note, had to modify generated code, it would be better to have this code elsewhere, even if it duplicates some of the generated code.
Added two sliders, now there are 3: CO2 source and sink and proton source.
Fixed some widget names.
Aiming to get history to build up each time "Simulate" is pressed.

Struggling to get array append working, still broken.
Also, Set hard coded step count per solve to 500.
Committing python code that is generated by QtCreator, just to enable debugging of pure python even when QtCreator and related tools aren't setup.
