-// The string array uses it's knowledge of internal structure of the wxString
-// class to optimize string storage. Normally, we would store pointers to
-// string, but as wxString is, in fact, itself a pointer (sizeof(wxString) is
-// sizeof(char *)) we store these pointers instead. The cast to "wxString *" 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.
