This class implements the queue's node. A node stores an instance of the specified (template parameter) `TYPE`, and provides an accessor `isUnconstructed` that indicates whether the value of the node was correctly constructed. If `isUnconstructed` is `false`, then the value (`d_value`) refers to a valid object. If `isUnconstructed` is `true` then `d_value` does not refer to a valid object, it does not represent a value in this queue, and the destructor of `d_value` should not be called. The specified (template parameter) type `RECLAIMABLE` is used to provide a compile time optimization for the footprint of this template when the value of `isUnconstructed` is known at compile‐time. If `RECLAIMABLE` is `false` then it can be determined at compile time that the construction of `TYPE` will uncoditionally succeed (e.g., it `IsBitwiseCopyable`), and the `isUnconstructed` property does not require a data member to be accessed at run‐time.
