Helper class that manages interactions between checkpoint selector, model display and model selection.
1. Showing geno without checkpoints -> disable checkpoint selector, enable model selection, pass to model display
2. Showing geno with checkpoints -> enable checkpoint selector
2a. Checkpoint selected -> disable model selection, display selected checkpoint
2b. Final stage selected -> enable model selection, display final stage
