    @header CFArray
    CFArray implements an ordered, compact container of pointer-sized
    values. Values are accessed via integer keys (indices), from the
    range 0 to N-1, where N is the number of values in the array when
    an operation is performed. The array is said to be "compact" because
    deleted or inserted values do not leave a gap in the key space --
    the values with higher-numbered indices have their indices
    renumbered lower (or higher, in the case of insertion) so that the
    set of valid indices is always in the integer range [0, N-1]. Thus,
    the index to access a particular value in the array may change over
    time as other values are inserted into or deleted from the array.

    Arrays come in two flavors, immutable, which cannot have values
    added to them or removed from them after the array is created, and
    mutable, to which you can add values or from which remove values.
    Mutable arrays can have an unlimited number of values (or rather,
    limited only by constraints external to CFArray, like the amount
    of available memory).

    As with all CoreFoundation collection types, arrays maintain hard
    references on the values you put in them, but the retaining and
    releasing functions are user-defined callbacks that can actually do
    whatever the user wants (for example, nothing).

    Computational Complexity
    The access time for a value in the array is guaranteed to be at
    worst O(lg N) for any implementation, current and future, but will
    often be O(1) (constant time). Linear search operations similarly
    have a worst case complexity of O(N*lg N), though typically the
    bounds will be tighter, and so on. Insertion or deletion operations
    will typically be linear in the number of values in the array, but
    may be O(N*lg N) clearly in the worst case in some implementations.
    There are no favored positions within the array for performance;
    that is, it is not necessarily faster to access values with low
    indices, or to insert or delete values with high indices, or
    whatever.
