/* The <OrderedCollecting> protocol inherits from the
<KeyedCollecting> protocol.
The <OrderedCollecting> protocol defines the interface to a
collection of elements that are accessible by a key that is an index,
where the indeces in a collection are a contiguous series of unsigned
integers beginning at 0. This is the root of the protocol heirarchy
for all collections that hold their elements in some order. Elements
may be accessed, inserted, replaced and removed by their index.
