5Informal protocol and utility function for making efficient deep copies of
6immutable collections.
7
8It is implemented in such a way that all objects can be deep copied. Objects
9that implement the NSCopying protocol are automatically copied, while others
10are retained. The following special cases exist:
11 * NSStrings and NSValues (including NSNumbers) are uniqued - that is, the
12 resulting collection will only include one (immutable) copy of any string
13 or number.
14 * Arrays, sets and dictionaries deep copy their contents.
15
16For objects where the mutable/immutable distinction exists, the result should
17be expected to be immutable.
18
19This self-optimizing behaviour is similar to that performed by binary plist
20export.
21
22NOTE: in accordance with Cocoa coding conventions, methods and functions with
23Copy in the name return objects owned by the receiver.
