-/**
- This is (yet another one) String class for C++ programmers. It doesn't use
- any of "advanced" C++ features (i.e. templates, exceptions, namespaces...)
- thus you should be able to compile it with practicaly any C++ compiler.
- This class uses copy-on-write technique, i.e. identical strings share the
- same memory as long as neither of them is changed.
-
- This class aims to be as compatible as possible with the new standard
- std::string class, but adds some additional functions and should be
- at least as efficient than the standard implementation.
-
- Performance note: it's more efficient to write functions which take
- "const String&" arguments than "const char *" if you assign the argument
- to another string.
-
- It was compiled and tested under Win32, Linux (libc 5 & 6), Solaris 5.5.
-
- To do:
- - ressource support (string tables in ressources)
- - more wide character (UNICODE) support
- - regular expressions support
-
-@memo A non-template portable wxString class implementing copy-on-write.

-/** The string array uses it's knowledge of internal structure of the String

- string, but as String is, in fact, itself a pointer (sizeof(String) is
- sizeof(char *)) we store these pointers instead. The cast to "String *"
- is really all we need to turn such pointer into a string!
-
- Of course, it can be called a dirty hack, but we use twice less memory
- and this approach is also more speed efficient, so it's probably worth it.
-
- Usage notes: when a string is added/inserted, a new copy of it is created,
- so the original string may be safely deleted. When a string is retrieved
- from the array (operator[] or Item() method), a reference is returned.
