* More filling out of parent/child unit tests. * Found a bug in the process. Removing a focused child does not reset the parent's activeDescendant state (it was using child.set("focused", false), which is readOnly. Changed to child.blur(). Fixes #2531907

Fixed issue where previously rendered children, added to an empty parent, would not get rendered into the parent's child container node. Based on the pull request from andreas-karlsson, with the root fix *and* unit test (nicely done): https://github.com/yui/yui3/pull/25 Fixes #2531093

Added additional check in _uiAddChild, to make sure prev/next sibling is rendered before trying to insert content relative to it. NOTE: This fix is not really required for the out-of-the-box parent/child implementation, but came up because a user had a custom impl. which made child.render() async [probably a valid usecase for parent/child]. See Fixes #2529863

Use extension destructor support, rather than AOP'ing destructor, which won't work. Fixes #2529785

Remove "Y." from @param and @return types yuidoc doesn't link class types that start with "Y."

Fixed WidgetParent remove, to remove child from DOM also. Added tests cases. Fixes #2528911

Fixed WidgetParent remove, to remove child from DOM also. Added tests cases. Fixes #2528911

Changed 'type' to 'childType' when adding children using the object literal notation.'type' is still supported for backward compatibility, but 'childType' takes precedence, Fixes #2529422, #2529280

instanceof to Y.instanceOf, to prevent mem leaks in IE7. See #2529344

Add @uses ArrayList for API doc linking

Fixed API docs for addChild, removeChild events. Fixes #2528795

Added prevSibling check to WidgetParent _uiAddChild logic, to cover addition of first child

Fixed incorrect index being passed around in the WidgetParent addChild event facade, and fixed logic in _uiAddChild to allow for decorator elements in the WidgetParent child container (came out of TabView Add/Remove Tabs example, which introduces a dummy decorator tab, which acts as a add tab button but is not really a WidgetChild)

Changed focusedChild (back) to activeDescendant. Turns activeElement is supported by the A-Grade, and is in the HTML5 spec. Also changing it to descendant, rather than child seemed to make sense as the low-level state, since only one widget actually has real focus. activeChild can be calculated from activeDescendant. See #2528688

Renamed activeItem to focusedChild as per comments in bug report. Fixes #2528688. Also cleaned up some temp sandbox files.

Added _childrenContainer property to allow WidgetParents to define where their children should be rendered. Defaults to parent's contentBox. Fixes #2528687

added WidgetParent::selectChild
