Fixes #399
Originally I just wanted to add
accessibilityLabel
to Tab Buttons to use them in UI Tests.However, when I looked into this I found that Tabman was not accessible at all.Whit these changes, Tabman is now accessibly without any changes required by Users of Tabman.
The most important change was for
TMBarView
to implement the (informal) (UIAccessibilityContainer Protocol)[https://developer.apple.com/documentation/uikit/accessibility/uiaccessibilitycontainer], which basically just needs to return the elements in the container (in this case the buttons).
