Class VirtualizingCellUIElementBin<T>

This class implements a cache of UIElement of the given type parameter T. It is used by the VirtualizingCellUIElementBin<T> renderer to recycle UIElement elements for cells that were scrolled out of view and delay unloading of UIElements. This reduces the number of times the UIElement needs to be created or unloaded and instead only the contents of the UIElement will be reinitialized with cell contents.
