The CounterfactualExplainer has several limitations.

• SEARCH DOMAINS:
  • Structures and Collections: disabled
  • Strings: Disabled
  • NUMERICALS: Must have distinct min and max values (i.e. min != max)
• GOALS:
  • Structures and Collections disabled
  • Strings: ENABLED

These need to be handled/reported in the UI.

If ANY original input is not supported; e.g. NOT UNIT then Counterfactuals need disabling completely.
