/**
* A Tree displays data organised in tree hierarchy.
*
* @accessibility
* Implements [ARIA TreeView](https://www.w3.org/TR/wai-aria-practices-1.1/#TreeView) design pattern.
* @accessibilityIssues
* [Treeview - JAWS doesn't narrate position for each tree item](https://github.com/FreedomScientific/VFO-standards-support/issues/338)
* [Aria-selected and aria-checked are not output correctly for trees #432](https://github.com/FreedomScientific/VFO-standards-support/issues/432)
* [Aria compliant trees are read as empty tables](https://bugs.chromium.org/p/chromium/issues/detail?id=1048770)
* [VoiceOver narrates "selected false" for DOM with role=option and no aria-selected attribute](http://www.openradar.me/FB8050959)
* [VoiceOver does not support Aria 1.2 listbox role owning unselectable group role](http://www.openradar.me/FB8050958)
* [Tree as table in Mac > VoiceOver narrates " no selection " when user navigates to tree/table](https://bugs.chromium.org/p/chromium/issues/detail?id=1273538)
* [Tree as table in Mac > VoiceOver narrates " 0 items enclosed " when user navigates to expaded treeitem](https://bugs.chromium.org/p/chromium/issues/detail?id=1273540)
