//  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.
//  5) there is no Insert() method because you can't insert an item into the
//     given position in a sorted array but there is IndexForInsert()/AddAt()
//     pair which may be used to optimize a common operation of "insert only if
//     not found"
//
// Note that you have to specify the comparison function when creating the
// objects of this array type. If, as in 99% of cases, the comparison function
// is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below
// is more convenient.
//
// Summary: use this class when the speed of Index() function is important, use
// the normal arrays otherwise.

// ----------------------------------------------------------------------------
// WX_DECLARE_OBJARRAY(T, name): this macro generates a new array class
// named "name" which owns the objects of type T it contains, i.e. it will
// delete them when it is destroyed.
//
// An element is of type T*, but arguments of type T& are taken (see below!)
// and T& is returned.
//
// Don't use this for simple types such as "int" or "long"!
//
// Note on Add/Insert functions:
//  1) function(T*) gives the object to the array, i.e. it will delete the
//     object when it's removed or in the array's dtor
//  2) function(T&) will create a copy of the object and work with it
//
// Also:
//  1) Remove() will delete the object after removing it from the array
//  2) Detach() just removes the object from the array (returning pointer to it)
//
// NB1: Base type T should have an accessible copy ctor if Add(T&) is used
// NB2: Never ever cast a array to it's base type: as dtor is not virtual
//      and so you risk having at least the memory leaks and probably worse
//
// Some functions of this class are not inline, so it takes some space to
// define new class from this template even if you don't use it - which is not
// the case for the simple (non-object) array classes
//
// To use an objarray class you must
//      #include "dynarray.h"
//      WX_DECLARE_OBJARRAY(element_type, list_class_name)
//      #include "arrimpl.cpp"
//      WX_DEFINE_OBJARRAY(list_class_name) // name must be the same as above!
//
// This is necessary because at the moment of DEFINE_OBJARRAY class parsing the
// element_type must be fully defined (i.e. forward declaration is not
// enough), while WX_DECLARE_OBJARRAY may be done anywhere. The separation of
// two allows to break cicrcular dependencies with classes which have member
// variables of objarray type.
