Enable uniform use of an optional integral constructor argument to specify the initial internal capacity (in items). For example, ` const Queue<int>::InitialCapacity NUM_ITEMS(8)); Queue<int> x(NUM_ITEMS); ` defines an instance `x` with an initial capacity of 8 items, but with a logical length of 0 items.
