+// This is the same as the previous macro, but it defines a sorted array.
+// Differences:
+// 1) it must be given a COMPARE function in ctor which takes 2 items of type
+// T* and should return -1, 0 or +1 if the first one is less/greater
+// than/equal to the second one.
+// 2) the Add() method inserts the item in such was that the array is always
+// sorted (it uses the COMPARE function)
+// 3) it has no Sort() method because it's always sorted
+// 4) Index() method is much faster (the sorted arrays use binary search
+// instead of linear one), but Add() is slower.
+//
+// Summary: use this class when the speed of Index() function is important, use
+// the normal arrays otherwise.
+//
+// NB: it has only inline functions => takes no space at all
+// Mod by JACS: Salford C++ doesn't like 'var->operator=' syntax, as in:
+// { ((wxBaseArray *)this)->operator=((const wxBaseArray&)src);
+// so using a temporary variable instead.
