Accessibility

[mjarvis]

An important part of this framework is to allow for verification and testing of accessibility support.
In enabling this, we should ensure that all of our views + controls themselves are accessible.

This includes:

• Exhibition and its list items
• NavigationView controls
• DebugView
• ParameterView variants

It is likely a number of these areas are already well-supported due to being stock iOS views, and most of the focus will be around the parameter views.

Verify screen reader properties and actions are as expected and the exhibition can be fully used via accessibility inspector.
